When I ordered this tool I was concerned it might not be strong enough for the job I needed would consisted of removing the clay, stones and roots. I'm happy to say that the harder I squeezed, the better it worked. Two relatively minor complaints - it's not clear which oil to use (not included) and the secondary handle moves too freely. It would have been nice if the spec of the best oil to use was clearly printed on the instructions and there was a way to lock the secondary handle.
