I like the product, but there are points I consider for safety reasons (mostly electrical), this is because it is usually connected directly to the battery, and two motor connection points are open, therefore, a short circuit of the pump does not last long. I carry this pump on my dual purpose bike where rain and mud are not only expected but required. I also covered the pump motor connections with tape for the same reason I added a fuse. I don't want 7.5 amps flowing into me if I accidentally short the connections with my hand or other parts of the bike. Now I'll say it works and I can inflate my tires as needed and while I haven't had to do a full inflation out of an empty one there's no reason the pump shouldn't work properly. I've removed and re-tightened all the bolts just because I do that for pretty much everything I put on or wear on my bike that can knock your teeth out of your head on long rides.
