I do scorekeeping work for a popular NYC basketball rec league. I just put the Tachikara in use and couldn't be happier. it's extremely light but not delicate and it's easy to operate. the numbers flip over effortlessly and they are visible in large gyms.
I carry it with me to all my assignments and it weighs no more than a tuna fish sandwich. fits into a small bag, too.
I recommend this piece highly.
Seems well made, yet light to carry but it should have flip cards for OUTS ( baseball). Also , numbers are one ONE side only of each card. I bought vinyl stickers to make it two sided.
Bought this for my son's football team. Its partially my fault for not researching it better but it is not very big. It's less than 24" big. I wouldn't of bought it if that information was included in the item description.
