This is an updated review. I have changed my review to 5 stars after contacting the company with a problem I was having with the lid. I spoke with a representative within hours of contacting the company, I did not have to beg or plead with him, he assured me that he would send me a new lid and it would fix my problem. Less than a week later, I recieved my new lid, which in fact, did fix my problem!The other day I left the bottle in my car overnight and was very surprised and impressed when I opened it the next day and there were still ice cubes in it. Container does not sweat either.Since these containers have become so popular, I hope people make the choice to purchase a fantastic product from a company who cares about their customers as well as our environment. Maybe this will push similar companies to follow KindHumans lead.I purchased both the Teal 32oz (for myself) and the Black 40 oz(for my husband). We both love them. The bottles are beautiful and the quality is excellent!The bottle seals tight, there is no leaking, the water stays cold for HOURS, and the bottle isn't too heavy to carry on walking trips. The health and environmental benefits of the bottle being zero plastic, are added bonuses!I love this product. When I’m shopping, I like to choose products based on the ethicality of them. I like using products I can feel good about. I applaud the manufacturer for getting involved in ocean cleanups and removing a pound of plastic for each product purchased. A manufacturer that cares about the planet is one that I can stand behind. Additionally, these bottles are very well insulated and keep the temperature of your beverages stable for long periods of time.This is a very very nice bottle. Keeps the water cool and fresh. If you make sure you fully screw the lid on, it does not leak at all.And very well made.I can comfortably carry it by the handle but for my wife the metal is too thin and so it’s uncomfortable.I got the 40 oz black bottle. So far I've only used it for icewater. I LOVE it. Lid screws on well. No leaking or sweating. Stays cold for a very long time. Perfect size for me to stay hydrated for hours. Very functional in size, shape, weight, handle and materials. Zero plastic, all stainless steel and works like a charm. This is an incredible value. Also my favorite color is black and the size i wanted was black so that sealed the deal.It seems like you can usually only get two out of three: Affordable, High Quality, Enviro-Friendly. However, after a lot of research, I found and purchased the Kind Humans stainless steel water bottle. It looks great, it's sturdy but not heavy or bulky, the lid screws on tightly, it doesn't leak, water stays cold all day, it was much more affordable than similar brands, and best of all: ZERO PLASTIC. This product deserves to be popular. Good job, Kind Humans!I was looking for a friendly environment bottle for some time.liked the simplicity of this one (I got the pink one), it has no plastic component just as described, and it keeps cold liquid for more than 24-hour period.It actually preserved ice cubes in it for even longer.I love this water bottle. 40 ounces is just about perfect to last me for a long work day at the office. I add ice to my water because I like it cold, and it is as cold as 6 pm as it is at 7 am when I leave the house. The lid stays tight and does not leak. Overall great product.
