1. Only 10pcs is not any kind of order. 2. Normal working hours 4-10H, depending on working mode, customer is using stong mode and expecting 24H working which is very.... you all know that. 3. Buyer wants perfect product, with cheapest cost, it does not make sense. He paid for what he got (good product, normal working hours). If he prefers whole night working, he should pay more to get another model.
