ReNu Reviews 

The brush is fine. What’s not fine is ordering a single brush kit and then having my credit card charged $43.49 every week since without authorizing it. I’ve been told that a full refund is processing for the THREE additional charges thus far, but have yet to see it reflected on my card. Buyer beware this scam. It’s especially unfortunate given that the product is marketed to those of us who are just trying to take care of our pets.

my pets seem calm for grooming i cant always tell if the mist is coming out, also i have so much product i dont know how i will ever use it all . my brush rarely goes dry

I bought a brush and was charged for a VIP membership I never agreed to. They charged £50 total for a plastic Chinese brush worth £5.

Asked for a refund and instructions for sending that brush back and they stopped responding.

Stay away from these fraudsters.

Update:
They responded here, but they keep sending me advertising emails, 3 since this morning alone, without addressing the issue with my order.
They are very unprofessional.

SCAM....MAKE WEEKLY CHARGES TO YOUR CREDIT CARD AND NEVER PROVIDE A REFUND...

WHEN YOU SEND AN EMAIL THEY RESPOND WITH A PREFORMED EMAIL PROMISING A REFUND THAT NEVER COMES.........😡👎👎

I ordered two brushes on 8-10-26. They charged me 42.79 and then 14.99 for the second one. On 8-14-26, they charged my acct another 42.79. I got the two bushes on 8-19-26 and neither charger fit the wand and the mist was hit and miss. I emailed the company and they were going to send me out new wands. On 8-24-26, they charged my acct again and i called and they said it was the membership fee and since i had access to benefits, they couldn't refund me but would cancel the membership. Well they continued to charge me on 9-1-26 and 9-7-26 42.79. I called this time and they still did not want to refund money. Said my membership had not been cancelled. She said she was canceling it then but started off stating they couldnt refund the money. As it stands now, she is supose to refund 128.37 of the membership fees within 3-5 days and suppose to send replacement wands out. Keep an eye on your bank acct

Received the brush but with only one bottle of mist instead of the 4 ordered. Also took a charge from my bank, when I emailed about it I was told it was for a subscription which I did not ask for and that as I had already had a month of benefits they would not refund. How can you have a month of benefits when you order on the 30th and then they take the subscription on the 5th of the following month so barely a week and not a month. I will be contacting my bank regarding this as money has been taken fraudulently.

Can someone from ReNu please contact me regarding the reply you sent. Since then I have had no communication regarding the missing products or the refund. There have also been no replies to emails sent through your site. I would appreciate some sort of communication so I have an idea of when the refund will happen or the missing products dispatched. Thank you

I ordered the brush and it was fine. It felt cheaper than I’d expect for the price but worked ok.

What I’m upset about is the FIVE times I’ve been charged this month! I didn’t knowingly sign up for any subscription. In fact, when I went to the website to check, it said I didn’t have any subscriptions. Why have they charged so many times? I will be reporting this scam to my bank.

They’ve charged my credit card $43 every two weeks since buying the pet brush. No new product has arrived, NOR did I order more. I’ve emailed many times and they say they are trying to fix it. It is a SCAM.

I bought the pet brush for 39.99. It didn’t work. The charger didn’t work. I just used the brush. In the meantime they charged me 39.99 3 more times in one month. They said I was on a subscription. Who charges a person 4 times in one month for a subscription. I asked for a refund and they only refunded me 39.99.
In my opinion this company is a rip off. I was was charged 160.00 dollars for a broken brush. BEWARE

Decent for what it is for my double coated husky it helps with surface dirt but doesnt reach well down into the deep undercoat

I ordered the dog brush, which was fine, but they started charging me $43.48 every 2 weeks for a VIP membership. I never signed up for that. My account showed no active subscriptions. I did not receive any emails regarding a membership (although I did receive many, many other emails).

This company was prompt, simple, efficient and easy to use once i received the product! I was well pleased the moment I used the product!

Update 9/13/26: The company claims that they will reverse the charges, but no surprise, haven’t heard from them in regards to that. They called me last week to give them a review?! Most random thing ever. Also, I went to charge my brush today with the charging cord they sent with their brush. ITS NOT EVEN THE CORRECT CHARGING CORD FOR THE PRODUCT!! The brush requires a USB C, they sent a MICRO USB. I stand by my rating, and would rate ZERO if it was possible.

CRAP PRODUCT and charged three times! Buyer beware. The brush is cheaply made. The mister does not work. I bought the “Starter Grooming Kit” for $39.99 + tax for a total of $43.23 on 8/15/26. On 8/18/26 my order was processed and then 10 days later the product arrived on 8/28/26. I was charged on 8/20/26 for $39.99 and then again on 8/27/26 for $39.99. Three charges all before I even had received their crappy product. I emailed them asking why I had been charged three times and said they needed to refund me immediately. They responded back apologizing and saying they would reverse the charges. They NEVER did. I didn’t sign up for any sort of subscription and even if I had unintentionally, why would I be charged 39.99 seven days apart? I then contacted my bank who is now dealing with it on my behalf.

Did not mist. Contacted customer service and contact person said that they would send another device. Have not received.

Recently checked my bank account and was charged 3 times for what I received. Emailed Renu, no response.

Did not received replacement and was charged 3 times. Do not buy

I was able to remove so much fur. Really
Helps get at the undercoat.

A lot of hair comes off, and my dog loves it more hair comes off with this product than any other brush I don't and I've owned several

Our dog liked being brushed, her fur felt softer and smelled the good.

I have been writing emails back and forth with this company’s joke of a ”customer service team” Since July 17, 2026. They have answered a couple emails saying they will escalate this or get a replacement or issue a refund. They have done NOTHING but ghost me. That is bad business and I will leave a review once a week to bring down your star rating until you refund me. GIVE ME MY MONEY BACK! For a company supposedly located in Denver, Co…you run this business like you’re based in China and you don’t care about your appearance to the public or any customer service. You should be embarrassed.

I am currently on the phone with their customer service team and will be recording exactly what happens for an up to date outcome…
Of course they act like they have never even heard of me or a problem with my order. Despite the fact that I have tons of emails proving the opposite. 1st they offered me a 30% partial refund and to keep the product. THE BROKEN PRODUCT THAT CANNOT BE USED! Then she offered a 60% refund. Now I’m letting her know she can put me on the phone with someone over her who can actually help me bc I won’t accept anything other than a full refund. And now I’m on hold again. 21min of wasted time arguing about an unusable product that they don’t want to refund my money for. 26min later and they finally want to give me a full refund bc I said I was recording this and will be including the interaction with my next review. I sure hope I see that refund in the next 3-5 business days as promised or I will be leaving another review. SHAMEFUL CUSTOMER SERVICE!!! DO BETTER!!

Finn is my Australian Shephard, and he has a massive thick coat. Keeping him brushed and cleaned of burrs is almost impossible. He HATES being brushed.

The first time I set up this brush and forced him to sit so I could brush him; he showed his displeasure by curling his lips and showing teeth. That is his way of showing me he does not like something.

I started brushing his chest. This is one of his worst spots to get burrs. After a few moments of lip curling, the teeth started to disappear. After 5 minutes of brushing, he laid down on his side and actually sighed! I told him to roll over so I could get his other side, but instead he showed me his belly! (grin) Not long after brushing his belly he actually rolled himself over so I could brush the other side! On his own! I was shocked!

The first brushing removed so much loose hair that I filled up a small trash can to the top and tightly packed with hair. He looked like he had lost weight. He hips and butt is the worst as the hair is the longest and thickest there. I remove massive amounts of hair from that area alone! It was amazing.

So far, it has taken me several days of brushing to get him pretty much cleared of loose hair, burrs and matts, but he comes over and sits for me to brush him with no lip curling in sight!

His coat is now shinny and clean feeling without a bath. He does not scratch like he did before all of this and best of all? No more Finn colored "Tribbles" (Star Trek reference - :) all over the house!
