I wouldn't buy this again [SEP] I wanted something my mother could use by herself. She had a stroke and only has use of her left hand. This is a great concept however, if you keep the cup on the counter, there is a lot of splash. I tried to show her how to hold the cup and push down on this at the same time but it's difficult for her. So now I just put some in the cup for her which really defeats the purpose of her being able to do it herself and I noticed even with 2 hands and holding the cup right under it, it still splashes on my hand holding the cup.
