I bought the Powertec track for my WEN track saw. Will update the review accordingly afterwards. The two brackets came zip tied together and that was it. They are exactly what I was looking for! All in all - excellent feel to them and they look the part. (comfy tho) It is suppose to adhere to your case, but the stickiness it is not great for me no matter how hard I press. Talla perfecta. This was easy to put together, all pieces needed were in box, there was a smell but I wiped wheels off put a floor fan to blow on it a few hours, no problem. Buenos audifonos.
