4v li ion screwdrivers

[bazfalty]

does anyone use these or 3.6v versions. I was just wondering if they are any good. I have an 18v makita and was just looking at these at being handy for how small they are if I've got to fix a load of trunking or conduit.

I have a 3.6v version and it is pretty poor tbh. No real power or torque. Just about enough to screw the M3.5 screws in on a faceplate! I know sparks who use the Bosch 10v screwdrivers on everything inc board changes (terminal screws) and swear by them.
