Review on ProForm 67605 Valve Spring Compressor by Lonnie Batch

This thing. This is the best valve spring compressor ever made! I made both heads (on a workbench) in 15 minutes! And there were no springs or detents flying around. Didn't feel like I had to wear armor making valve springs with this tool lol. Only thing, no complaints in case you're wondering, this tool doesn't work with Gen4 rectangular connector heads. Just the port of the cathedral! (as advertised)
