I wanted something light weight to take with me traveling. Something that would not clank around on my day pack. I think this is going to be beyond perfect. I was amazed at how really light this is.... no pun intended - since it also has a fairly bright light in the cap (with three modes) that can be recharged with the USB cable included. I pray that this does not leak since I can see great possibilities for happier days of travel. One of my stainless steel springy mixing balls fits inside (even when folded) and will allow me to travel with my protein powder and green tea powder. All the comforts of home on the road. YEA!!!!

Product is overall a great buy. Its footprint is able to be smaller when not in use as you can fold it. However, you can siphon the air out of the bottle when less and less water is in there(so hardly any water is sloshing around). This helps backpack sway when I'm out hiking or taking the bike out for an urban ride. LED lighting is helpful for ambient lighting when hanging out in the dark. I recommend thoroughly washing it before use as not doing so may end up giving an off taste but it quickly disappears.

This is a nice lightweight water bottle. It’s great for travel or any outdoor activity. It’s neat that it lights up, charges with an android input cord, making it nice to use in the dark. It stores small in luggage and in the cabinet.

This is such a cool water bottle! The folding/rolling ability makes it so versatile and convenient to bring anywhere. Also the light feature is great! I love this bottle and recommend it to anyone.

I took this on a two week trip. It worked fine for a few days but then sprang a leak.

 Went backpacking with 2 of these water bottle, awesome vessel for holding extra water and doubles as lamp.

Question, can this be brought onto the plane in my carry-on?

Ideal product but poor quality. Light button stopped working and would randomly turn on and off on its own.

This is a really great waterbottle! It lights up at night and can be used for a variety of purposes. Great for hiking, biking or even music festivals. I love the fact that it is collapsible and folds for easy packing.
