Heavy-Duty Air Pump with Gauge

Fair Price-to-performance Pump

Used for many air-powered rocket launches. Each pump will last about say about 150 launches. In my classroom setting, that means they need replacing every three years or so with heavy use during these launches. Students who have never used a bike pump can figure out how to utilize these, and even with misuse, they do okay! Have been used with water-bottle rockets as well and they seem to hold up well to potential water intrusion. Pressure indicator is helpful and haven't failed yet on these pumps unlike other models. In comparison to other pricier, fancier pumps, these do the job and last about as long. I recommend these pumps. They likely won't disappoint. Some points of failure I have experienced include the valve coming off of the attaching hose, and plastic footing breaking off, though I suspect it's largely due to student misuse.
