One simply doesn't start and the other, a trimming chainsaw, has a broken adjuster.
Neither are particularly old - both are Landi (OKAY) ones. Sounds like an excuse to buy a Stihl one
Good stuff - it's amazingly powerful for its size and extremely battery efficient (a full day of assembling furniture and the battery is as good as new), really light and handy. Even the hammer function is working well and is pretty well suited for quick drills in brick walls, as long as holes are less than 6mm in diameter.
Bad stuff - the drill head is not perfectly centered, meaning it's not really well suited for drilling jobs (can't make a clean drill) and the problem is magnified with longer drills.. It's a common problem discussed on forums and concerns both the "GSR" and the "GSB" models from the Bosch 10.8V line. It didn't bother me at first, but now does.
I probably would not buy it again because of this problem.
Instead, I would look at the Metabo PowerMaxx 10,8V with the angle-adapter (which doesn't exist for the Bosch line)
If you're only rarely going to be drilling concrete for small holes like hanging pictures, then an all in one cordless driver/drill/hammerdrill is probably the right thing for you.
For anything more (more often, larger holes) than that, get two drills, they can even be the same, but dedicate one to non concrete usage. The hammer function is hard on the whole mechanism, and the concrete dust trashes the chuck pretty quickly.
I have a rechargeable hammerdrill from Jumbo with SDS chuck since about 6 years. In the meantime I have a large enough selection of SDS bits that I was able to discard all my plain shank concrete bits. For concrete holesaws I use a line powered drill.
My tools are subjected to something close to professional use. So far it has usually been the chuck that has gone because of concrete dust. Since I separated the two tasks, the machines I use for non concrete jobs are holding up better than before.
The charging station on the Bosch is much better, as it also holds ten or so bits and the tool is left permanently resting on it, whereas the Lidl one is a simple plug-in charger.
I doubt you'll find any modern tool that doesn't give a sufficient level of reliability, so I'd go for cheapness and convenience if making a choice now.
Lidl have an offer this week on a 4-in-1 drill/screwdriver/saw/sander thingy for 99 chf.
Must admit I'm currently being very tempted by a Ryobi 18V cordless hammer drill and sander (separate tool) for the boat, the whole toe rail needs sanding and revarnishing this year. The Ryobi system comprises lots of tools that all use the same battery system. Anyone come across it and have any feedback?
