Review on 🎒 ROCKRAIN Hydration Backpack: Stay Hydrated on Outdoor Adventures with Insulated 2L Water Bladder - Ideal for Hiking, Running, Climbing, and Cycling - Perfect for Men, Women, Kids - Lightweight Daypack by Jimmy Koroye

So it's frustrating when you get paid for something that's defective and then have to fix it before you can use it. Because he was booked for a specific day and couldn't just return. The mouthpiece didn't work. Upon inspection, I saw that the seal was basically a rubber band. Like the ones used for braces or something like that. Very cheap and free. So much so that it moved once the mouthpiece was fully installed. Causes a leak. It just couldn't adjust to the spot so I replaced it with a better quality o-ring.
