That review may be right about it being a "light weight" puller. To be a little more fair, I think it could probably do medium duty as well (whatever that means!). It is a nice puller- light, pretty strong, and it fits in tight spaces and in unusual positions. Those are the 2 qualities I most appreciate.. The other puller at our shop is a big greenlee puller on wheels. I have had the pleasure of hauling the greenlee up 3 storeys in commercial buildings and would much rather have had the Maxis (we didn't have it at the time though..) For resi underground subfeeds it is ideal, but for longer pulls of larger wire, you probably need something bigger.
