Sometimes I hear myself talking about how much I love this drink bottle and have to stop myself to realise that the majority of the population probably thinks I'm a little bit nuts but seriously when it comes to cups this things is the bees knees! Super tight locking mechanism, haven't had any spills in my bag. Remarkably easy to clean. Looks great! It's awesome when a company can do something simple so damn well and these guys have left no stone unturned.

Only comment would be around customer service - my feeling is (as with most small startups/kickstarter projects) there's a VERY small team behind this product who are probably overwhelmed with enquiries. A sent some enquiries that weren't answered until much later and even the USPS delivery was a bit odd when mailing to Australia (kept getting updates like "your package has arrived at a facility in LA on March the 2nd and will be delivered on February 27th - ;D) but it arrived in the end!

All in all I was so happy with the product that I'm not really bothered by the above!

Well done.

I was looking for a great bottle, that would hold up in my daily living. The cap is nice and secure and gives me confidence that it will not spill when tipped over. I know I’ll be ordering another one in a different color.

I love the HIIT bottle!
It stays hot or cold for longer than claimed and it looks amazing!! The bottle is nice to hold and the attached loop is very convenient! Easy to clean and use! Twist top works perfect and doesn’t allow any leaking. I want another one!

My HIIT V3 comes everywhere with me. It is awesome for hot and cold drinks. I use it mostly for protein shakes, water and coffee and it keeps their correct temperature for about 24hours.
There is clearly a lot of thought behind the design and it is really well engineered.
Definitely worth the price!

I have thrown out all of my other bottles - I use my HIIT Bottle for everything

Shipping added another 10 dollars that I wasn't expecting. For that price I would have expected faster delivery. Items didn't fit inside shipping box, they were poking out of the top. I use the hiit bottle every day and it functions as intended, but there is room for improvement. The lid is too difficult to unscrew, so it probably needs deeper, more numerous grooves to grip. The tea infuser should be on the bottom of the bottle so it contains to infuse as you drink or you can have only a little tea if you want. You can't use infuser for tea unless bottle is full, in other words. I'm using a drop in tea infuser ball instead, it functions a protein shaker too. If your tea infuser could be detached and dropped down into the bottle it would be great. The top of the lid is taller than necessary and I don't know the purpose of that shape. There is already a place for a lanyard so why another hole in top. At least fill the lid with insulation if it's going to be big like that
