Review on Speensun Automatic Foaming Soap Dispenser With Infrared Sensor - Hands-Free, Touchless 450Ml Pink Soap Dispenser For Kitchen And Bathroom - USB Charging by Tim Wilson

I bought two of these overpriced gadgets because the Conbola (https://www.amazon.com/gp/product/B07R55TFMM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) was out of stock. (It seems to be available now.) This unit has the main advantage of the Conbola, which is that is it rechargeable by USB cable. But (a) it has less capacity, (b) has a top-heavy design that makes it less stable, (c) doesn't emit soap unless the user's hand is almost touching the sensor, (d) is rather complicated to turn on and set to the right amount of soap, and (e) both of the units worked intermittently and have now failed (as of 10/24/20). If I replace either of them, it will be with the much less expensive Conbola. I would award this item -5 stars if I could.
