First of all I can agree with the one star rating that this tool is not built to last. But after spending three days prying the valve stem through a hole in my motorcycle rim, this little Hummer did the job in five minutes and is worth its weight in gold to me. For the price I order a few extras and have them on hand in case one breaks. At the same time, be careful when ordering similar tools, as the nuts are too large in diameter at their ends to fit through the hole in some rims.
