Let me start by saying this automatic soap dispenser is a game-changer for maintaining hygiene, especially in high-traffic areas like bathrooms. The hands-free operation via infrared sensor is flawless – it detects your hand instantly and dispenses just the right amount of soap (about 0.8-1ml per use). No more germy pump handles!

The 21oz capacity is perfect for families – I only need to refill mine every 2-3 weeks. The transparent chamber makes it easy to monitor soap levels, though I wish the plastic was slightly clearer as it can be hard to see the exact level when using opaque soaps.

Installation was a breeze with multiple mounting options. I used the included adhesive strip which has held strong for months. The lock design with key is brilliant for public spaces – no more stolen soap dispensers!

Now for the quirks: The battery compartment cover feels flimsy and requires screwing/unscrewing which might wear out over time. Also, like some reviewers mentioned, the lid doesn't sit perfectly flush when locked – not a dealbreaker but noticeable.

Pro tip: If your thick soap isn't dispensing well, try adding a few drops of water to thin it slightly. And definitely use quality batteries – cheap ones will have you replacing them monthly.

Despite minor issues, this dispenser has saved me money on soap (no more over-pumping!) and keeps my bathroom looking sleek without clutter. For under $30, it's been worth every penny.
