Second go around.
Didn't get a chance to use the first one, but so far the replacement is ok. Tightening screw on first one broke when mounting and started weed eater. Screw broke and threads were down inside.Item was replaced right away.The 3 stars is because of hardware quality.

Works great!
I do maintenance for a golf course where weedeaters are used daily. I have bought several of these, and so far they are working perfectly. Each one saves about $150 off the new price price of a new weedeater.

Poor quality , not reliable.
Got the head in as promissed , it was defective , the seller was prompt to replace it , which I appreciated.The replacement was also faulty , so again I contacted the seller , but , unfortunately, he never responded even aftet 2 notifications ! Too bad , I can't give him a good rating !I bought one from a local distributor , and the weed eater is fine.
