First off, way too expensive for what it is. It should be half the price at best. But, fool me once right? Anyhoo, it works but the adjusting thing on the back comes loose fairly easily so you might have to adjust a few times depending on how many you're bottling. The 3 stars is mostly because I'm still surprised it hasn't snapped in half from trying to take bottles out and put them in. It bends quite a bit making me think "ok, this time it's going to break." Thankfully it hasn't yet.
