Unfortunately, the shop delivered a different product. I returned it to the seller, said I no longer want the ordered product, and asked for a refund. The shop received the package but did not return the money. It’s been about 14 days. Therefore, I do not recommend this shop.
The product stopped working after a few days. The cause was the battery. It either didn’t charge or was old after a long time in storage. After replacing the batteries, the device started working again.
