I received this product for free for my honest review. The first thing I noticed about stainless steel drinking is how amazing it feels and the quality of its perfection. I noticed that this came with a straw and a straw cleaner brush, which we all know can be a pain when washing straws with these cups. The color is very vibrant and easy to spot. My drink literally stayed cold all day. I kept putting more fluid in, but the ice held up extremely well, so this I would consider very well insulated. The design of tbis bottle is completely thought out. When I had sweaty hands from working, this was still very easy to grab and drink. The least, but most importantly, this bottle is leak-proof. This is definitely worth the price.
