This is good but it leaks  after a long time so it's good to get faucets with it for that day when it might go bad.

Changing my review from 5 stars. I thought this thing was awesome but it leaks.

I've been using this for 2 months now. In the beginning it was great but now it's always leaking no matter what speed I use or how slowly I feed the vegetables through. It's really annoying and messy. I've talked with others who have this model and they aren't having this issue so I don't know what's up with mine.

I loved this when I first got it. So nice and keeps my ice water cold for hours and hours. But much to my dismay this started leaking after only a months use. Not sure if I got a bad one or what but sure wish it would have not started leaking because it sure does keep your drink cold.

I gave this two stars instead of only one because it was SO easy to clean.  It didn't matter, however, because within a couple of months, it started leaking.  It doesn't matter now how tight I get it, it still leaks.  I read the other reviews and should have known.  I'm guessing the only reason some people have given this more stars is that they haven't had it long enough.  Once it starts leaking, it's all over.

Works well and is definitely leakproof. However, finished scratched in normal use within the first few weeks and has scratched several times since.

it's great but some parts(the attached photo) need to be tight very well and some times there is some leakage.

I really liked this water bottle. I would have given 5 stars but it started to leak after a short amount of time. If I screwed the lid on super tight it would be ok but then it was difficult to unscrew the lid to fill it back up.

Started leaking after a few months but my husband superglued around the glass view part and I am back in business.  I use this many times a day.

I had no problem with leaking, unlike the reviewer below. It is true that you have to pull it down every time you want to use the spray function, but that is not a big deal for me.

The problem is it didn't last. I used it for about 9-10 months and then it broke off in my hand when I went to use the spray function. If it had lasted, it would have been a good buy, but I don't feel the price reflects the low durability.

I bought four of these, and within a week two were leaking. (The other two lasted about two years without leaking.) The seal in the lid doesn't seem to stay in very well.

Other than that it's great: really durable, looks like new even after a year.

Overall it does its job.. Only thing I dislike is that it leaks even though you close it.

This is the second one I have bought.  It doesn't leak and it works well to begin with.  After a while, the valve on my last one became worn such that water would come out of the filter and the faucet at the same time.  At first, I could wiggle the valve to make it stop but eventually I could not stop it.  It takes a while for it to mess up.  Based on reviews of other filters, I find this one acceptable because at least it works well for a while, rather than messing up to begin with.

These are good durable bottles but they leak easily unless threaded just right. One of mine leaked all over my car seat and even wet my tablet. If you're putting it inside of a bag, be sure to hold it upside down first to be sure.

Works great but after a while the tip of the mouth guard leaks even when secured tightly. I take it to work in my lunch box and when it comes to lunch time I already have a puddle of water at the bottom of my lunch box. Bought two of these and both do the same thing

We still own this product, but at first we had leaking problems. You really have to screw the bottles in good and make sure all the seals are closed. I do like how they measure out shots for you, but it can get messy if you don't check all the seals and closures. It's a good product, and it's lasted a while. I don't really use it all that much, but it is nice when you have liquor that you do regularly go to. And it's easy to mix drinks.
