This unit does what it says it does. Quality is great, and it's easy to use. Pads are ok. I only use as MEDI and for that it works perfectly.
But I would NOT recommend this product... Why? Well product is shipped with firmware 1.0 you can download new version with a ton of improvements from Alesis, but but but a lot of people has problems with the firmware update, just like me, and Alesis does not respond to support questions!!!! I had to find the fix for the problem in a FB group... That is insanely bad customer service. Complete useless, and what happens if something else happens to the unit!!!
If you read this and you have problem with your devise, you can find help in the Alesis support group!
