Review on Dsycar 6 Pack Gold Metal Valve Stem Extenders - 45°, 90°, 135° - Universal Extensions for Car, Motorcycle, Bike, and Truck by Thimothy Purnell

So far they have worked very well for me. I have 3 bikes and over the years it has been a constant struggle to get the air inflation hose onto the inflation valve at just the right angle. The fact that this is a set of 3 (six pairs) is what made me buy it initially and I was wondering if they would all work as well as there are three unique angles. I was pleasantly surprised to find that they all work because all I really needed was to have an elbow, any elbow, on the inflator valve and now attaching the air hose to each of them is much easier. there was no problem with pressure loss or retention or anything. So far so good, hope they last for many more years. If I run into any issues I will update this information but for now 5 stars.
