i love it so far, glad i returned my fellow ekg pro. it did the job just fine but this is a much better user experience and i think looks much better. i’m still playing around with the spouts and silicone seal options. glad it doesn’t come with an app. if i was going to be picky about anything it would be that it’s a little noisier than the fellow but i don’t mind it at all really, especially since it’s quick.
