"I like that it’s stainless steel and easy to thoroughly clean. The “loop” on the top is poorly done - it’s uncomfortable to grab and it came off which sent my bottles tumbling on the pavement as I was walking. The weld is weak. Fix this and it will be great."
"My intent was to avoid plastics in my water bottle. Paired with my stainless steel 27oz bottle this lid does just that. Looking forward to getting a 64 oz stainless steel bottle when they are back in stock and pairing it with this same lid. Great products from Kleen Kanteen."
"It is so easy to throw into the dishwasher and go! My husband is obsessed with his bottle."
"Bought two to replace older flip top lids. Works great."
"LOVE this bottle lid! I highly recommend it. Fits great, well made, works as it should. I appreciate that it is plastic and chemical free, and I can swap it out for the bamboo option - at a very affordable price. I will be buying more as spares!"
"The caps are functional, they seal just fine, however they can be a little noisy when screwing them back onto the bottle. The carry handle on the cap is spot welded and can support the weight of a filled bottle, but are a little delicate and can break free (it did on one of mine). They're serviceable and functional, just a little fragile. If they're going to see light use, these should serve you well. If you're looking for something a little more robust, maybe look into purchasing the bamboo, the carry looks to be a little more durable."
"Plastic free!"
"This is a very sleek, low profile cap that looks great on the bottle. You would need to add some sort of string to comfortably carry the bottle as the opening on the cap is only big enough for a single finger, but it is a nice cap."
"works great, light weight easy on and off."
"Light, looks great, holds a lot more water than other bottles of same size. Does smell like iron the first two uses, but after no more if you keep had washing."
