I purchased this lid because I dropped my water bottle and the original lid, or one of the many replacements I've purchased, broke. Normally I would have purchased the spout lid, but they usually sell out quickly. This lid functions as it should, water stays inside the bottle and it screws on/off easily. I'd still prefer the spout lid but I have this one in the event that I need it. I'm really looking forward to the upcoming improved spout lid, hopefully it won't break every time I drop my water bottle.

Works well, very satisfied

It works fine most of the time. As long as you don’t over tighten it the chance of it just popping off is pretty low. Also, putting it on was a pain, but it’s probably made that way to lower cost so I can’t complain.

I bought three of them because the other lid type would literally explode on contact when falling from any distance. (I broke two of mine and three from two other friends.)

Does what it was meant to do.
