Everything is positive (choice, site, product quality, advice) but delivery quite deplorable: I was not informed of the delivery, in my absence (extended), the delivery person (TNT ??) simply left the packages along the wall of the house (fortunately it's the countryside, very little traffic), the boxes took several showers, a bit light for a 1000 euro order! Fortunately the content did not suffer (barely!) despite boxes beginning to decompose. Why was I not contacted before delivery? This is the only downside, which costs one star in the final rating, the battery is magnificent.
