I am one hundred percent satisfied with the purchase, I recommend this product to everyone.
The choice of shifters is not great. The next level, subjectively, is a fanatic, but the price there is very different. TH8A works out every that is asked for it.
Pros
Great shifter. Easy to set up. Quality materials and assembly, nothing to complain about. Included is a mod for the box to work in sequential mode (did not use, no need).
Cons
The translation on the box and in the instructions was run through a very cheap translator. There are typos and errors everywhere. It does not affect performance, it can not be considered a minus.
