## Customer Reviews

### ⭐⭐⭐⭐⭐ Piccolo e poco ingombrante
*by C***N on 28 February 2021*

Dimensioni ridotte, quindi per l'uso di un accelleratore sono ideali. Ottimo prodotto

### ⭐ No
*by A***H on 17 February 2024*

It not good and missing one piece

### ⭐⭐⭐⭐⭐ Work well enough at 3.3v. No reverse polarity protection
*by J***S on 14 May 2020*

After killing one by powering it backwards, I found the rest of em all to be working well at around 3.3v. They stopped working below 2.8 volts. 10k and 100k pullup resistors worked. I didn't see a reason for a filter capacitor but my supplies are generally clean enough. Field direction matters! If it isn't triggering with the magnet on one side, try the other. And the thin, magnetic sheet used on a lot of fridge magnets was not strong enough to trip these switches, either at 3.3v or 5v. Stronger magnets worked just fine. Packaging was: in a small zip lock plastic bag, wrapped in foam, wrapped in yellowing cellophane tape. I was kind of worried about static but they seemed to be okay otherwise.
