Review on 🏞️ AONIJIE Pack 2 TPU Soft Hydration Water Bottle: Collapsible Flask for Marathon Running, Hiking, Cycling – BPA-Free & Convenient for Hydration Vests by Shannon Connolly

First Use and Disposal.1. Arrived with NULL instructions2. Instructions for washing and removing the bite guard will be emailed to you. NULL response.3. Water seeps out from under the screw cap and more when you squeeze the bottle. Applying petroleum jelly to the threads did a squat.4. The small diameter causes the bottle to fall through the bike bottle cage.5. To get water to flow, you have to bite down hard on the tip. Good idea, mediocre design, bad material. I do not recommend.
