They use them about the shop and seem to find them useful. Me, I have my 3.6v Panasonic cordless screw drivers that have lasted and even excelled over the last eight years without problems other than dead batteries. This and the newer 7.2v DeWalts as a similar product that all you have to do is replace the battery once bad, or swap out for the extra while in use.
Don't know about the little pup type screw drivers but batteries and long term use over the years might be a factor. On the other hand, ergodynamics and if it lasts a few years might be payoff enough in buying a new one.
Primary question than is how long it needs to charge up before use and how long that charge lasts in the next three years before disposing of this desposible tool?
Add to that blade lock in being able to further tighten a screw beyond battery torque, and trigger lock for transport - a PITA when a trigger is touched otherwise in wearing down the battery before use. In the past such tools needed either really small battery inserts that wear down fast or the tool to be plugged in for like an hour between running out of
juice which progressively got worse.
Wombat as this item appears as if appropriate... yep, they are about at work but I don't know anything about them - nobody asked me what might be best for use about the shop. I will have said one of the above other tools.
