Query: Cracked Cylinder Blues

I'm going to throw my lot in with the people who are not recommending this product. It's the perfect size and just what I wanted. I give it two stars because when it was working, it was exactly what I wanted. It's small enough that you can get good targeted injections, unlike some of the huge stainless ones. However, the plastic cracked after just a few months rendering it useless. I don't know about you, but I prefer things to last at least a bit longer than a few months. I didn't even use it more than two or three times. Complete junk.
