The rubber pad surface came off as soon as i took it out of the box, i peeled away the old (now useless) adhesive and used some super glue and tape to fix it in place. Who knows how long that will last.
The pad does not come with assembly instructions so, while it is not complicated, you might make a few mistakes along the way.
The front lip (where you attach the pedal) can be adjusted somewhat and the pad has two screws on the back to help fix it in place. In my unit one of these is very hard to turn.
Overall it works fine even with a double pedal and it remains stable on a rug. I have no idea how long the pad will last, or the screws.
This is my first ever pedal practice pad so i have no means of comparison, but i am overall happy with the purchase
