This is a very substantial piece of kit, i was pleasantly surprised to see how heavy duty it is, baring in mine all the older types ive used. I think the main concern with equipment like this is, did I feel safe using it? Yes i did. At no point did it give me any reason to be concerned. Check your fitment, make sure everything is correctly lined up. READ THE INSTRUCTIONS. Be completey clear on how this device works and functions and you will be fine. I found the build quality to be excellent, sturdy and made of good quality materials. My only gripe is the yellow plastic padsnon the coil seats should be a bit thicker, i am nit picking but a little thicker would be better. I am happy with my purchase and if that changes in the future i will update this review.
