They gave me a total refund as stated on website I bought 2 collars for my 2 cats, and whilst waiting for their arrival I decided to dig deeper in to the safety of the ingredients (because I started hearing that essential oils were bad for cats). I read many different reviews from Amazon.com and Trustpilot about cats having bad reactions. Since my cats are indoor/outdoor cats I did not want to risk putting these collars on. So I emailed the company and explained my situation. Without any further conversations Dewelpro refunded all my money back. I am so pleased with the way they handled my situation. With whatever research I found on these collars, in my opinion, they seem to be safer for dogs than that for cats at any age

Got here fast Got here faster than I thought. I am rating the delivery right now as the flee & tick season has not started yet, so I can not rate the effectiveness of the collar itself.

Great company and product I'm really glad I scrolled upon this company! I was leary the first order but I received my order quickly! I have now ordered multiple times and each time they are efficient and quickly send your items! The product seems to work well on my Golden retriever with sensitive skin! She has zero reaction to this flee collar and I haven't noticed any bugs!

Highly Satisfied Customer I first received one of these collars by accident. I put it on my dog and I was delighted by the results. No more scratched my and only 1 or 2 ticks the whole season. He was more comfortable immediately. This is important to me, also, because of Alpha Gal allergies. I love this product and plan to continue ordering. Thanks for a great job!

The best collar for my best friends I have been using Dewelpro for my 3 dogs for the last few years. I never worry about fleas, mosquitoes or ticks -and most of all I do not worry about putting toxic chemicals collars on my dogs. I only use them because they work and smell great too! Thank you dewelpro!
