Bought this to replace a cheaper one that had become a camping essential. These are great for topping off an inflatable mattress before bed, or inflating/deflating floaties. No more red in the face and dizzy trying to get a beach ball blown up! This one has the additional upgrade of a lock function, which is great for just chucking it in a bag and not worrying about whether or not it will get turned on a run down its charge. Feels quite substantial, for what it is, and I'm hoping the battery life will prove to hold up with use. Overall, would recommend for campers, beach bums, or anyone who doesn't want to pop a blood vessel in their eye trying to blow up a pool donut.
