Mainstays 64oz water bottle with straw

Overall a good 64oz bottle for staying hydrated throughout a day. Lid closes up good and can shake it with electrolytes mixes without leaking. I like the small cap you unscrew and straw pops up or “floats up” and you sip. Closes easily. Plastic wall thickness is decent as well for the price and the carrying lid handle seems sturdy but I carry it by the handle. I've dropped it twice full of liquids and bottle still doesn't leak. Impressed me. Translucent black also helps those who might mix vitamin or light sensitive mixes into their bottle.

I appreciate the fact that this had the ounces on the cup. I used this for my colonoscopy prep. This helped me out a lot! I could easily keep up with how much liquid I needed to drink. I highly recommend this!
