did what it was supposed to do. I have used it on some sti hd3 14 inch wheels. Before that I tried every method to install the valves including using lube and nothing. When that came too I used it straight away and slipped the valve through the hole with ease and didn't even need lube. and wish you had known sooner. The quality isn't great but it does the job and that's all that matters. I bet $10 is probably what a tire shop would charge for it, except you can keep the tool here :)
