I want to start by saying that I’ve been using Koi for a while and I can say it works! Also shipping is fast! Felt like Amazon Prime service lol! Anyway, it helps me with my neck pain and to relax whenever I feel nervous! Also I had a leaking issue when it was shipped but customer service was great and sent me a replacement! Thanks Koi!
