We like mainly the warranty that they offer. If you have any problem they solve it very quickly. The after sales service is also pretty good.

The quality is very good. The price is a bit higher than other brands but its performance fully justifies it.

We like this German brand because they produce a reliable product with very good quality, long living and low self-discharge rates. As a plus their distribution is good, and their post sales service is satisfactory.
