Probably the cheapo HF model I have then. No way it will break anything loose even remotely tight. Works fine once something is broke loose. Never had another model to try out. It is the same one I linked to in the earlier question.
Which is why I asked the question. You can use it just like a regular ratchet. Pull on the body, break something loose and then hit the air to finish removing it. I looked around here & there when I first got it to find out how it was to be used. Didn't find anything useful...
Even though I have several impacts and a decent compressor I usually just use hand tools. Helps my solid handshake grip ;-)
