Query: Very useful product and Good customer service

I really liked the product. It was very very useful, convenient and easy to use so I was disappointed when it suddenly it stopped working within 90 days. I contacted Amazon support who connected me to the manufacturer who immediately contacted me and is sending me a replacement unit. It's discouraging when you have a product you like and it fails prematurely but when you get great customer service immediately when you contact them and get a fast replacement all is well. Looking forward to using it again. I'll update this review if anything changes.
