There's quite a bit of slop (backlash?) in them but these are the only worm gears I've ever bought, I bought several sets, so I don't know what normal would be in terms of the backlash from different types of teeth patterns, etc or other manufactureres. As a commodity part they're fine and I'd recommend. Machining seems well done. They're going in 3d printers in my project, I can use firmware settings to electronically eliminate the slop or even use spring pressure or gravity to always force contact to a specific wall of the worm to get rid of the slop.

Drive gear listed as 5mm bore. Not so. Drive gear is 4mm bore. Had to machine it to make it fit properly.Other than wrong bore size on drive gear it worked out properly. Worm gear is 5mm bore

Inside dia of worm gear was actually 6mm not 5, and an Acura you of +- 1-2mm is not good when you are dealing with parts of 5mm size.
