Could be better
So happy to finally have a cap for the nipples but the caps don’t always 100% of them time fit on the metal ring. Only one side actually pops in and locks …. if you’re lucky. If there is a trick, I would be open to learning but I’ve had these almost a month, and they are still weird to use.
Hi Harpreet! Oh no, this must be frustrating! Please email email@example.com, and we would be happy to help.
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!
