First proform I ever bought was there adjustable shift light completely unreliable
Next was a TDC locator for a sbc spark plug hole would not thread in exchanged it for another one same problem
Lastly and I mean lastly was the valve spring presser gage that is used in a vice or drill press it did not even make it though one set springs before I started to get some fu#@ up numbers because the gage was and is still reading 50 something pound with no load on it
For me it’s been three strikes and proform is out
