excelente

Love it

So I read the reviews regarding this product, but it works. I found out a few things when trying to use it. First. You cannot tip or till the Tumblr at all. It has to remain straight. You cannot put a lot of ice in it and it has to stay under the max full line in the inside. I get flavor for the caridge on the lower setting. I don't think that you have to suck any harder than drinking from a normal straw. I like that it stays colder longer. It takes a few times to adjust to using but I think it's worth it.

Its not a STANLEY but it serves the same purpose. I don't like drinking plain water and this is perfect. The lid doesn't let anything drip out if it rolls over. Size is great 40 oz so 2 reg water bottles. If you fill it 3 times you went through one cartridge. I don't like fake or overly processed flavors. so its nice getting just enough and being able to control the amount of flavoring i get. I'm happy with the cartridges for now. I haven't been disappointed yet. I've been drinking considerably more water because of this bottle. Its built really well, so not disappointed. Its hit or miss on the ice retention. you have you balance out ice to water. The bottle actually keeps stuff pretty cool. I'm definitely OK with that. it does fit in most if not all the cup holders i have had to deal with.

This is an amazing product. The size alone is great to get in all your water supply for the day. It works great, just sip and go. The color is perfect and bright. The flavors of cartridges makes drinking water delicious.
