It does the job it should simply and nicely. I have used two such devices (of this brand) and I had no complaints from either.

Waste of money. The first one I had to replace within six months under warranty, and the second one broke shortly after the warranty expired. Stay awayyyyy

I worked with it for about 15 days, it's all over the place no matter how you adjust it. It either runs too fast or doesn't run at all, or it freezes and runs on its own, completely unreliable. I would prefer something else, from what I understand, all those without a photocell sensor have difficulty recognizing the hand with the two-point sensor system. The downside, of course, is that the batteries are located at the bottom, which eventually gets moisture. However, this particular one, which has them on the back, works differently

Top product. It takes a considerable amount of soap and since its battery is on the back of the device, there is no risk of moisture entering the mechanism (I have had three similar ones that had the mechanism-battery in their base)

Simply Wonderful. It does exactly what I bought it for. Without diluting the cream soap (it's not runny). As for the batteries, I can't have an opinion because I haven't been using it for long.

I had a Baseus one but after a year the plastic broke where it screws to hold the batteries, so I bought this ANKOR one. I use it with Antiseptic - Antibacterial 70% and it works perfectly like the previous one!!! as long as the liquid is not too thick.

ps
It is quiet!! compared to the previous one I had...

Very good product. I have been using it for at least a year. It hasn't had any issues. It works perfectly. I would buy it again!
