Astro tests, yes, and its likely better than the twister, but I still dont think its going to work near as well as an actual slidehammer will.
Once they get out to some users we'll start to know, but I got a feeling its just going to be "oscillating" and not hitting hard.
It's a vibratory tool vs a 10lb beast for sure just watching the videos.
If I buy one, it won't be replacing my monster sized slide hammers, it's a different tool. Plus, the swing is tiny. So even if a 1.5lb baby slide hammer would have enough grunt, that needs a 12"+ throw. I think this astro tool would work for stuck gdi/diesel injectors, bearing races, that sort of thing.
EDIT: anything will be better than the Texas Twister. My friends still tease me..... "I should have a tool for that"..... "The Texas Twister?!?"...
It still stings.
I would not buy one and expect to pull hubs or do wheel bearings with it. I'm not a physicist. But I'm betting a work shirt wrapped around a 10lb slide hammer like a sling on a 7/8 diameter rod will create a higher peak force.
