Plenty room for two scoops of protein powder or whatever you want. A lot bigger than I thought.

Dose Locker
Quick and easy to use. My husband and I have our own. We start each morning putting a scoop of our favorite protein powder in the dose locker. He tosses it in his computer bag for work, I toss mine in my purse. For lunch or a mid-day snack, we grab a water bottle, preferable a 24oz water bottle, take a few sips of water to make room for the protein powder, then unscrew the dose locker to empty powder into water bottle. Screw lid on water bottle first, then shake it up til looks blended. Great for on-the-go and traveling! We love it!

It helps
It's handy if you are traveling, and even if not but it requires a lot of tapping to get most powders into your bottles. You could just make a cone out of a paper plate and get the same if not better results. This is just nice because of the caps.

love the dose locker
I was buying one of the blender shakers and saw this at the register. So, I thought why not try it. I mean its nothing fancy, however, I love the idea of taking my powder drink in this cute little bottle and pouring it into my shaker bottle. Its small enough to fit in my gym back and the perfect dose of my powdered drink, In addition, no mess!! I no longer have to use plastic container and scoop. Perfect invention!!

Very useful product. Just pack my shake and this funnel with my powder and I'm good to go right after the gym. No scoop, no mess!
