So much for my experiences.
What I find questionable, however, the e-mail requests from Avanto (traders) to assess the product - most recently with the reference to 10% value of goods Refund in a good rating of the battery. I find that very, very, very serious. What is practiced here is deliberate manipulation. Whole lousy tour. So if someone is planning to buy another product, which is sold by Avanto, should the reviews on Amazon are again more critical towards. Who knows what sums have flowed in the background.
Reviews where someone the 10% reimbursement takes Traderjob begin with the Amazon order, at least it is pointed out in the e-mail to this to the review may be mentioned at the beginning to associate with the customer.
Conclusion: super product - Dealer not serious. Because of the latter 4 stars.
Oh yes: If Avanto because this Reznsion the idea come to me equal to reimburse the full value of goods if I should delete this review, I am not for sale, thank you!
