Delivery: 5 stars. Pricey but worth it, arrives from China to US in 2 weeks (samples).
Quality: 4.5 stars. I personally liked it. Unique plastic and rubber feel.
Design: 4.5 stars. Button idea is good, gentle for pet paws. One concern: Button design is uncomfortable, prefer the one in the picture. Still gets the job done!
Service: Loved it <3. Friendly and trustworthy, deserves more than 5 stars.
