Came quickly and well packed. Easy to connect. Installed the app. A lot of functions.

Excellent seller, received the package good condition.

Excellent workmanship! Chose from similar proposals where the description will specifically indicate the presence of the battery. A dollar more expensive, but without unnecessary hemorrhoids. Works perfectly, the backlight only works in an outlet, but it is also better-why waste a charge? And the clock works. I have not yet collected statistics. Upon arrival, the battery was completely discharged, but after half an hour everything worked as it should, the device survived the planned shutdown without failures. The order was shipped on the 3rd day after payment, arrived in 2 weeks.

19 days delivery. Tested everything works perfectly, already put it in the shield. The thing is necessary, how much will work be seen. I recommend the seller.

Producer. Excellent
