Review on 10 Pack of CSBD Clear 24 Oz Sports Water Bottles for Customized Branding - BPA-Free Food Grade Plastic Ideal for Fitness, Hiking, Cycling, Gym Workouts – Made in USA by Wendy Harris

bottles arrived safe and sound, strong, strong enough and looking good (shiny, shiny, nice finish). I'm excited to put stickers on them tonight for my son's birthday! But maybe I'm a bit snob, but the "nipple" is hard rubber, not soft rubber (which is normal for everyday use, but sometimes cyclists use their teeth to open it with one hand). Also, when flipping and squeezing, the thread sizes are too large and don't mesh (and/or the materials are too hard and don't flex enough) so they leak when you release or reapply the pressure.
