Adapter
Overall a good product, the only thing is that where the bits lock on isnt a very hard and secure lock. It doesnt seem like they lock in firmly. They stay for the most part but the adapter that locks in the bits you need to pull back towards the handle. Not a very clever design since you could easily unlock it while trying to squeeze in somewhere, especially hot panels. It does work but its something you have to keep in mind

Absolutely worth the money.
The media could not be loaded. I am an electrician’s apprentice and I recently got a raise, decided to buy one of these for my panel work. The new price tag was steep, but I was able to find a used (but essentially brand new just without factory packaging) for $165 and I could not believe the deal I got on this item. Seller was supposed to take a week to ship and it arrived 2 days later, so I really appreciate that as well. This kind of screwdriver is a giant leap towards no more hack jobs, and my overall experience thus far has been perfect.

So this works great, but perhaps not practical for most people
This works great but realistically if you're trying to tighten a screw to e.g. 45 ft-lbs you really should be using a wrench because it is really hard to keep a screwdriver in the screwhead and not strip it with that much force being applied.

handle
When using the higher inLbs settings (screw Lugs) the straight blade slips out of the screw slot damaging the screw and it takes alot of wrist strength to turn the driver. I didn't not believe the reviews until I tried the tool myself. It's a safety concern on energized circuits. The handle needs to be changed to a T-handle.
