    Comments about Seiko STH100 Metronome/Tuner with Stopwatch:

    I bought this for my husbands sister who lives with us, we had previously picked out a different product. I stumbled upon this site and found this metronome. I looked at all the options and noticed you could do several things at once, and was impressed. Libby loved it she said it is the best metronome she has ever seen. She is in All State Band every year and will continue to do well with the help of this product, Thank you.
