Review on IQ Labs Vitamin Powders Plastic by Amy Padilla

This doesn't suit me at all. The funnels are very small and the opening is not much larger than the standard opening. Product photos are misleading. If you look at the third photo in the ad, the funnel looks pretty big against the background of the bottle being filled. Not so. They are described as devices for loading powders into vials. It's going to take a long time to fill and refill these things to load the average amount of protein powder these hoppers are supposedly designed for. They are also very fragile and prone to breakage. They're very cheap, though, so the pain of knowing they're basically useless for loading anything other than a salt shaker isn't too unbearable.
