But quite well

After I returned the first charger, because I was not satisfied with the customer service made contact with me. I got a new charger sent. After a couple of written contacts turned out that the equipment is provided upon delivery with a film (which I noticed the scratches on it) should you before you use it, remove. That I had not done the first unit because I thought she heard it. An indication that they should be removed, I've noticed anywhere.

Without this film, the device is now working much better. But you should still an Accu, the power goes off when the sun disappears, and not enough energy enforcement, use as an intermediate charging station to prevent discharges. I had the first attempt.

I now also another 7-watt unit to another company tested and can say that it can stand a direct comparison. They both work with similar results.

Customer service I can only rate as very good.
