Very secure lid!
I loved my plastic rings with lids and was hoping for something similar for the metal lids. Sure enough, Mason Bottle makes one so I ordered it. At first I thought it wasn’t working & leaking, but my husband showed me that I just wasn’t pushing it on hard enough! I thought if I pushed too hard I might break some of the snaps, but that wasn’t the case. Very durable, very secure, and now that I’m used to it, it’s easy to take off and on! (Customer service was very gracious when I thought I had a defective product. Luckily I realized it was my fault it wasn’t snapping on all the way!)
It's great and works well. Very secure
I use this cover over both the nipples and the straws for when we head out. I'm still midful of it not being upside down and tossed around but so far I haven't had any spills! It works great!
Vents sometimes don't with
Convenient, caps work well. But sometimes the vents don't work/get stuck. But in general pretty good.
Works well, like the snap and easy take off. But disappointed they don’t fit the plastic mason bottle rings.
