I purchased the crack weeder as I had serious crack weeds in my parking area. I had tried all the tools in my belt, and I was down to getting a hellaciously powerful blow torch. Instead, I came across this little dude. I ordered and received it with absolutely no problem. That is until I couldn't get the blade attached. Now I must say my hands shake horribly, and I was unable to get the blade nuts on as the little useless wrench that prevented the tightening of the nuts. After about 3 days, I was able to get the nuts and bolts tight enough, and I haven't needed to use it yet.
