After using the Wisekoti P9 for 3 months in both my kitchen and guest bathroom, here's my brutally honest take:

The Awesome: That 0.25s sensor response is LEGIT - no awkward hand-waving like cheaper models. I dilute Dawn dish soap (1:3 ratio) and get restaurant-quality foam every time. The 4 foam settings are genius - setting #3 is my Goldilocks zone.

Battery Life FTW: Charged it once when unboxed and still going strong after 8 weeks! The Type-C port on top actually makes sense - no more fumbling with upside-down Micro-USB.

Annoying Quirks: Guests CONSTANTLY press the top button thinking it's the sensor (I finally put a "NO TOUCHY!" sticker). And that "drip-free" claim? Mine leaves tiny soap bubbles under the nozzle that dry into crusty rings.

Pro Tip: Use distilled water for mixing - tap water minerals clogged my first unit after 2 months (thankfully Amazon replaced it). The adhesive pads work shockingly well on tile, but skip them for granite counters.

Verdict: At $25, it's pricier than manual dispensers but saves SO much soap (my 12oz bottle lasted 4 months!). Just wish the motor was louder - sometimes I'm not sure if it actually dispensed until I see foam. 4.5/5 stars!
