I liked the performance of this gauge. It has a long handle and good grip, making it easy to line up and press against the tire valve. For bike tires, a long stem would be a problem, but they include an angle sensor that does the job well. The only reason I took off a star was because the first one worked great on day 1 when I used the direct sensor and then the angle sensor. But on the second day, when I was using the direct sensor, air started leaking out of the corner sensor, causing the tires to lose pressure quickly. I notified the seller and he quickly replied that he would send a replacement. Got a replacement and went through the same process of using both sensors and so far it's working fine. Another nice feature is that the display shows the battery level when you turn it on. But the battery level on the original and the replacement was just above zero. It has two types of batteries so not sure which battery level is showing. Also, the item came with batteries installed and no insulating tape that prevents these batteries from discharging. So I think the batteries may have died during storage.
