The service looks cool and has more features than free ones, but Its really overpriced for a service that only serves to take screenshots, even with some extra functions, its functions are pricey for the price asked (8 to 12 a month in a annual plan...)
If it had anything to compare parts and even take screencasts (gifs or movies), it wold be better than the current feature set for the price or even better, to be able to convert images to text, grids and etc to compare layouts....
Only for static images, its really expensive
Why should we pay for this service while there are many free services?
