Basically great device, but with significant shortcomings

Great functionality, which I do not have to continue to run here. I own the device a few years, so I can also contribute a long-term experience.
I want to broach only a few points here:
1) Refresh function to old batteries up on his feet: Here I am about the benefits now very much in doubt - quite apart from the fact that the process may take several days. Although the battery cell has then again about 80% of its former capacity, but this of course is not durable. May well be that it is only at 25% again next time. (Discard and replace them with better Eneloop batteries!)
2) Fully discharged batteries - even those that are basically still in good shape - will not be recognized! This is a serious disadvantage! I fortunately still a cheap old-loader, I miss such a battery start charging. They can then be loaded as normal with the Technoline BC.
3) The charging current gradation 200/500/700, I think at the bottom for too coarse. Especially for AAA batteries, I would like to see even an intermediate stage (350 mA).
4) The discharge current is only half as high. This takes a discharge / charge cycle of eg half-charged battery at 500 mA 2000 8 hours! (Also 8 hours for a semi-loaded AAA battery at 200 mA.)
5) The keys respond after a few years of getting worse. The my 6 years old appliance mode button works no longer, which is why I can now discard the device now. Annoying!

Altogether, some weaknesses and serious shortcomings have yet to list! I'll look around for alternatives therefore initially.
