I like how it works for different mobile OSs by connecting to their respective app stores (Google Play & Apple). It is easy enough anyone can use without prior knowledge about what each button does or even which phone they're testing from! As far as any dislikes go - nothing really came up while using this tool so all was good :D The price makes me feel nervous sometimes but if you stick through then end result will be worth every penny :) You get exactly whats needed in terms of functionality when paying money into an application development environment such has bit bar / ios apps dev kit etc..
