Great tool
Worked perfectly, easy to use.

probably works just fine
took a chance and bought one open box. Got what I paid For. the Item was received broken at the crankshaft end. someone was not instructed or did not know how to use it. Once the end is threaded into your crankshaft do not try to turn that end it will snap off. follow directions! I did buy another upgraded model from same company and have used it without issue... if you follow the directions should last a lifetime.

Not what others said it was. Great product
Worked great on my SBC. I read prior poor reviews yet this was nothing of the sort. It was sturdy, and worked as it should. If on the fence, my humble opinion is it is a great tool for the price and will be used again.

Tool threads need some prep
Bought this to install new harmonic balancer on my mark iv big block. It did the job. Took away 1 star because out of the package the threads were binding in the crank. So I needed to power wire brush the tool threads, then use thread chaser to clean them up. It worked but there was about half an hour of cleaning tool up before it was useable.

Great tool
Tool functions as should and I wish I had bought one of these sooner. Very solid tool. Needs to be used appropriately. If tool breaks off in balancer or damages balancer, it was most likely not connected correctly. There are many how to videos on the web demonstrating how to properly use this type of installation tool.

I received item broke
The item might of worked if it didn't come broke and the package looked as if it had been opened an then resealed. The company that sold it to me was great. They refunded my money an told me to go ahead don't worry about sending it back. Only problem I had was I had find another place that had one due to the company that sold me this one said that they didn't have another one to replace the one I got from them. So i had to send more money for another one in order to get it in a reasonable mount of time to finish the job. But all in all the service from you and the company I got the tool from was great Thanks for you service's
