i have them in mine and several customers. i have only had one gauge go bad (shortout). i havent had any problems with them other then that one and it was replaced for free. i have had an isspro boost and glowshift boost hooked up next to eachother when i first tried them and they were the same. the only bad thing about the glowshift that i have found is they dont have a big selection of gauges so if you want to monitor a bunch of stuff you have to get other gauges (glow shift doesnt have a gauges that can read high pressures for an air tank or so) overall im very happy with mine
