Ktslighttherapy Reviews 

2 x die Firma angeschrieben wegen Frage zur Anwendung. Keine Antwort erhalten. Für mich absolut unseriös.

Poor customer service. Like the other customers, I returned the lamp and was given several poor excuses why the refund was delayed. From blaming my credit card company saying the delay was on their end, to telling me I have to allow processing time, which by the way has been since April 30 when they received the lamp via FedEx in sellable condition. They now stopped communicating with me in general. To date, I have not received my refund. THE ONLY reason they get the one star is that it does not start the rating with a 0, otherwise that's what KTS's rating is a BIG FAT 0. UNTRUSTWORTHY, THIEVES. KTS SHOULD NO LONGER BE ABLE TO RUN A BUSINESS IN THIS MANNER!!!!!! THEY DESERVE TO BE SHUT DOWN FOR EVER AND NOT ABLE TO DECEIVE CUSTOMERS AS THEY HAVE. IF YOU ARE THINKING OF ANY PURCHASES FROM THIS PLACE, PLEASE BEWARE AND TAKE HEED TO THE REVIEWS. THESE ARE FACTUAL CLAIMS AGAINST KTS LIGHT THERAPY..

STAY AWAY!!

Ich habe einGerät für den Mund gekauft.Es sollte bei Zahnfleischentzündung helfen,was es aber nicht tat.Daraufhin wollte ich das Gerät innerhalb der 30 Tage Rückgaberecht Zeit zurückgeben.Der Kontakt mit der Firma war nicht möglich,daher habe ich mich an Paypal gewandt. Die konnten mir leider auch nicht weiterhelfen. Ich würde zukünftige Kunden gerne warnen,dass weder das Gerät noch der Service noch die Möglichkeit der Rücksendung oder Rückerstattung des Kaufpreises funktioniert. Ich habe also 100 Euro bezahlt für etwas, das in keiner Weise einen Wert hat.

I advised KTS on July 24th, 2026, that the light therapy device I purchased from them just a few weeks earlier had quit working. The device had a one year warranty from KTS. After numerous emails back and forth over nearly a month providing statements, pictures and videos, then waiting for their evaluation of the claim, I was told to return it to them. I was given an address, but told I would have to pay for the cost of shipping. This was the 6th of August. It cost me $35 to return the device to KTS in China. Then I waited. And I waited. About a week later I reached out for an update, as I had heard nothing and was concerned if a shipping snafu had occurred. I was told they would let me know when they received it for warranty service. 9.09.26 KTS advised no confirmation from them on shipment. KTS responded the following day (9/10) that the package had not cleared Customs. The same day I replied to KTS with the tracking number and a screenshot showing the package had in fact cleared Customs. KTS advised they have no control over over Customs and still not cleared. I complained to them about not standing by their product and warranty. On 10.06.26 I emailed KTS for a status report as I had still not heard back from them. I have not heard anything from them since. Nor have I received a new or repaired device. Awful company. Avoid them.

Terrible experience. Avoid this shop!I never received my item, and the tracking number clearly shows that the parcel has already been returned to the seller. I have followed up with the shop multiple times regarding my refund, but they keep making excuses and constantly dodging the issue. They have both the item and my money now, which is completely unacceptable. Highly irresponsible and untrustworthy seller!

I purchased one of their KTS product and did not like it. Returns are impossible as they asked me to return it to China on my expense. It cost more to return it to Chine than the item itself. I disputed the charges with my credit cart company and they decided to my favor. You cannot call the company. Emails only.

Scam ! Do not use this company, my elderly father purchased a red light therapy lamp from this company, he never received the parcel, they initially said they had sent a replacement but Evri keep saying the postcode does not match what is on the parcel and keep sending it back to the supplier, requested a refund but now not responding to emails !

SCAM. Found out that the products are not FDA approved, just “registered”, which means nothing. Wrote to request a refund and the company went back and forth with me for 6 emails trying to convince me to keep the product instead. Finally got approval for a refund and had to spend $50 at the post office to mail the product back to CHINA (even though the return address on my delivery was in California). Still haven’t received a refund. BEWARE

Falschen Artikel erhalten und musste Retoure nach China selber tragen und die Annahme der Retoure wurde vom Händler verweigert. Mir wurde ein Gerät teuer verkauft, was bei AliExpress nur 14€ kostet. Kts ist der reinste Betrug!!!

I was given a KTS Light therapy device for pets. There were no instructions in the box so I emailed the company. Several Emails backwards and forwards after I was asked for my order number and sent them photographs of the box they didn't reply to my last email and kept on insisting that they needed an order number and I kept on reminding them that this was a gift. Appalling Customer Service. I now cannot use this device in case it causes harm by misuse.

Advertised they will accept returns within 30 days for any reason if unused. Advertised as easy return. What they didnt tell you is that it has to be returned to China to the tune of $300 via UPS.

Terrible faulty item worked for a day, says massage but there isn't. Now telling me I have to pay for return do not touch. Bank now involved, but they are refusing to help do not use

I purchased from KTS Light Therapy because they advertise their products as “FDA approved.” After purchasing, I asked multiple times for proof of this claim. They ignored every request and provided no documentation.

I searched the FDA database myself and could not find KTS Light Therapy or their products listed.

They have also ignored all of my emails and questions (sent Dec 6, 11, 16, 25 and Jan 11, 12). Zero response.

KTS Light Therapy’s false FDA advertising is what convinced me to buy. Their lack of transparency and complete absence of customer support is extremely concerning.

I would strongly caution others before purchasing from this company.

Reported to FDA/BBB.

I purchased the KTS handheld vitiligo device last November, and the shipping was incredibly fast—it only took 3 days from California to my home. After over 2 months of phototherapy, the white spots on my face are visibly shrinking, with the edges clearly filling in. The results on my fingers are a bit slower, which is expected due to the thicker skin, so I'll continue the treatment. The device itself is compact, easy to carry, and delivers great results. I also want to give a shout-out to Cindy from customer service; she’s been so patient and provided so much helpful guidance throughout my treatment. Highly recommended!

I have been trying for months to return RTL knee therapy massager.
My pain escalated to X3 , I contacted them and said it was not suitable for me. They were initially sympathetic and asked me to forward photos of the device ready for return, which I duly did. They then ghosted me and have not replied to any of my emails.
Do not buy from this terrible company. Not even sure if the device is legitimate, it doesn’t fit snuggly, and the only setting is 20 mins.

Achtung, hier bloß nie etwas kaufen. Defektes Gerät erhalten. Rückgabe nur nach China, obwohl es aus Deutschland kommt. Das kostet 49 Euro. Obwohl ich es zurück geschickt habe, habe ich nie mein Geld zurück bekommen. Händler antwortet auch nicht mehr. Keine Hilfe von Paypal. Pech gehabt. 230 Euro mal weg.

Ordered by mistake, tried to cancel within 1 hour and got ignored for 2 days until they came back with the update that the order had been shipped. When in fact I had not received a single email confirmation on shipping. I asked to send me clear return and refund instructions, no response again.

Just appalling customer service. Cindy, who is apparently a marketing director and takes time to just send you meaningless responses, is not able to cancel the order or provide any clear refund instructions.

Big mistake but will sort it out through the bank.

Scam! Good luck getting support or refund from this company. Per their policy, they inform buying to reach out to customer service to approve returns, yet they never respond to emails. I have attempted several times to reach out, only to be ignored. No response from them of any kind.. no answer or emails. Their reviews on their site are fake, just try to write one , it won’t let you. So I came here to hopefully inform the next potential buyer to go elsewhere for any purchase. This company is not legit and while you’ll receive either junk or broken product, your chances or getting it replaced or refunded is zero. Shop elsewhere

Terrible customer service. I purchased a light therapy kit in April 2025. I returned the package unopened which they received on May 10. They have still not processed my refund as of November 2025. I’ve been presented with so many excuses for not refunding my money. I filed a dispute with my credit card company. KTS lied to them. I presented evidence of the return and the emails from KTS to me, but the dispute window closed without resolution from Capital One.

So, I write KTS often to demand a refund, Still no resolution.

Never buy from this company!

They sold a tanning lamp to me that had bulbs intended for reptile cages in.

I had burns and blisters all over my leg where i used it, for only ten mins.

UVB is 30% in the bulb which is 5x the legal limit for humans.

they also lien about being in the USA, they are based in hong kong and all of their certifications are faked.

you can't find them through the FDA or CE which are the two main ones.

they sent me a forged CE certificate which i had verified to be a fake.

stuck with a tanning lamp that burns your skin and they are not responding on refunding or returning the lamp.
