Requires round batteries (not included)

I honestly haven't tried it, and unfortunately it doesn't have batteries and the ones needed are very hard to find in my country 🥲, but other than that it looks exactly like the image and is very practical.

Very good product, it is of good quality, you need to buy the batteries for it to work.

Product received as described, will have to see over time if it really works.

It looks good but it comes without a battery.

Hello! I received it quickly, you need to include a battery, in the photo I show you where and what model of battery it uses.
