Customer Reviews
This is already the third UPP I've purchased for MTB. There have never been any problems with the previous ones either. The seller is always available to resolve any issues, which, in truth, have never arisen. This time there was a slight delay in delivery, which the seller promptly informed me about. The BEST batteries. Buy without fear.
The order arrived well-packaged at the post office, although it was supposed to be delivered by a courier, but that's not a big deal. There was a slight delay of 11 days. But visually everything seems fine. You can buy it.
Delivery was delayed due to weather conditions. The seller responded to inquiries and warned about the delay. Packaging was excellent. The battery is intact. There is a label from LG. Haven't tested it in use.
