First off, these were purchased without the idea of buying a truly first rate tool as I'm not a plumber by trade, but with the understanding that I would use them at some point as my position does include facilities/utilities maintanence.So, with that in mind I thought great price...? I'll make em' work. But, when I received them I was very disappointed. The wrenches themselves were packaged all together instead of individually and looked as though they had seen YEARS of abuse. Secondly the adjustment screws/dials were very quirky...they would stick in some positions and were not able to fully open and close on a few of the wrenches. Sorry, but even for the $40 I paid for these I couldn't see myself having to fight these things to work... Also, I tried to reach the company who I purchased these items from to see about returning them and kept getting an answering machine for three days and no return phone calls from them. I tried to like these, but with the condition and way they where packaged when they arrived, along with the poor customer service, these tools were a lose-lose to me.
