Bests & Worsts Reviews from Amazon

I initially gave this product a very negative review. I was testing it out in my condo and it often times couldn't find the device or took a very long time. I turns out that my bottom floor brick condo is very close to being a dead zone when it comes to data and cellular reception. I get a signal on my phone but it is very weak. When using the device in more typical situations it performed exceptionally. I'd like to add that when there are a lot of competing products one of the things that separates one from the others is the customer service. The customer support I received from Whistle was far and beyond what I'm used to.
