Review (5/5): Great product
Very happy with this product. I read a lot online about the proper way to fill it, and had no problems. It is a rather large bottle compared to how much it stores, but I like this over the pumps with the tube in the middle, so it's worth it to me.
Tips:
1) fill almost all of the way full. You'll need to make sure there aren't air bubbles. So order the smaller of the sizes that you want to store. Screw the cap on tightly.
2) If it doesn't worth, tip it upside down, tap on hard surface (to get the air bubbles to the bottom), and take a paperclip to push the bottom up as far as it can go.
It pumped well, filled easily and was a reasonable price. Would recommend.
