One is the Harbor Freight chinese knockoff, another is the Porter-Cable electric impact wrench. I broke the HF wrench in about 90 days and HF sent a repair kit....HF is VERY good about sending repair kits/parts free...the problem is their stuff breaks often. I bought mine for 19.95 about four years ago. HF can't get rid of these tools so they dump them every few years.

The HF tool is adequate, but I don't think it pulls 250lb-ft. Neither does the Porter Cable tool. Both are too big to move around for a lot of jobs which is why I use a pneumatic wrench if at all possible. IOW, I haven't used the electric wrenches since I got the pneumatic ones.

If you're in the VA/MD/DC area I'll sell you the HF tool for $20. As soon as I can find it...I think it's packed away in temp storage until we move into the new house, prob sometime in April.
