So here's a weird one... I think it's better than sliced bread. My wife hates it. When I showed her how great it was she replied "that's stupid". I said what do you mean? She said "look, it spills all over. It's stupid and I can't believe you paid for this!" Her friends all agree. Wow! Is this a female thing?
I love my speed stir, but am on the fence with regards to the sample sizer. I always used a bottle with a small cap that allows me to easily add water until I hit either 10 or 25ml. I purchased a sample sizer about two months ago, and while it works, I don't find it any easier to measure samples. And it does make a mess - I never spill water with my other method.
I have been singing the praises of the sample sizer for a while now. Who cares about spill over, I’m always filling over my sink anyway. The sample sizer and speed stir are Indispensable as far as I’m concerned.
