I bought this for a final project on one of my engineering courses, it never turned on. I shouldn't have sent it back as I won't get a usable one in time. So I found another solution instead. Aside from not working, it looked and felt like a good device. If you don't mind the possibility of a defect, this pump is probably a pretty good option.
