I think these buttons have been pushed 10000 times, its well made, sturdy and im glad I bought it.

the clicking mechanism is pretty good and should hold up ti a lot of use. My kids have had a lot of fun playing with this tool, even without focusing on the math to be learned.

Excellent concept and kids love it. It's great for visualizing how addition works. I do wish the numbers were printed on, rather than stuck on with stickers, though. Some of the stickers are eroding after light use.

Love it

as described great

Im loving it

Spent a lint time playing with this with our 5 year old granddaughter yesterday, she loves it.

My kids love this addition machine! It is very well made, and worth every penny to build up early math confidence!

This is a handy educational tool for math, HOWEVER the white sticker tiles are made of paper and when wet, crumble deteriorate off. Lasted for a few days.....I took the time to cut pieces of clear tape on the stickers I could save....but its still not the same, and was very inconvenient. I wish it had something to protect the equations from moisture or for easy cleaning and wiping.... :(

Purchased the multiplication machine for my 3rd grader and my first grader is fighting over it with her so I came back to purchase this machine. Kids love pressing the buttons and it’s helping them memorize these math facts easier than flashcards because they look forward to it!

my daughter loves it, ill have top buy the rest soon

I was pleasantly surprised with how much my children engaged with the Addition Machine. Even my toddler loves pressing the buttons. Maybe she'll be a math whiz!
