Pulse : Good idea but still needs development

The general idea is pretty cool, feeling the beat instead of hearing (especially when playing loud drums) can be very helpful BUT:

* It sometimes looses the tempo and isn't super accurate, which makes it impossible to use it in practive for me for tempos above 120-140

* If you put the vibrations higher, then it is also longer, which exacerbates the point above

* The application is paid with a subscription ? You get 3 month free if you buy this device but basically if you want to be able to use it to its fullest potential you have to pay a subscription every month. For a product that is tagged at this price, I would expect it to come free.

TLDR: Good idea on paper, but on practice it feels more like a gadget. Also the paid subscription for the application feels like they are just trying to grab as much money from you as possible.
