Great product technically in view of competition

I am using the LaCrosse BC charger 700 for almost a year and as I am almost certain that the difference with the Technoline 700 BC, it's just the brand, I can judge the quality of the product:
Most:
- It acts as an independent 4 battery chargers
- It supports AA and AAA batteries
- It helps to know (about thanks to the tension) on a battery charge level
- Very simple user interface

Nevertheless, this still be improved:
- Excessively discharged batteries are not recognized (for my part, I first charging them with another charger that accepts)
- The buttons are pretty steep: you sometimes press repeatedly for the charger to realize that you pressed a button.
- Perfectible design (I hate the external power supplies), the case is not very nice (as well as having an object lying around at home, so it is pleasing to the eye), but I've seen more ugly. Moreover, perceived quality is not great either (I do not judge here of the actual quality of the product, it's just that the materials are plastoc I would for my part agreed to pay 10 euros more for noblest materials).
