Bright colored fun retro calculator
Cool, solid calculator. Got it for my son to play with. Nice bright colors. Very lightweight. It's fun to take the cover on and off. Operates perfectly. Comfortable size to hold in the palm.

Does what it says but is not purple
Nice quality calculator- I bought a second because only one came with a math curriculum I bought for twins. It's a good calculator with a convenient case. Do be aware that despite the photo, it is blue, not purple.

Although the pictures show purple it is blue... The picture is misleading!
This is a great little calculator. I use to teach with all of the time. The picture shows a purple calculator and the text says blue. I find that misleading. I would have bought it anyway it was blue. But I was excited to have one in purple so I can tell mine apart from my kids.

Great calculator, BLUE not purple
This is a great calculator. It’s a bummer the bad reviews due to color. My kids use this for math at home. Gets the job done. Surely with this many reviews an understanding has been established that IT WILL BE BLUE!!!!!!

Not purple
The calculator arrived and it is navy blue. Doesn’t look at all like the picture.

Not happy- Can’t return not an amazon product apparently
They gave me the wrong color. I ordered lavender and I got blue, but it still works well. Kind of disappointing because I was buying lavender to all match.

No es el color qué muestran en la foto, la compre por el color... No vale el precio.

Picture is of a purple calculator. But it is a royal blue like what others have shared here. Functionality could probably get 4-5 stars but this seller should have changed the photo along time ago it seems.

Works great but wanted to suprise my daughter with a purple calculator for school (her favorite color) and we got blue… I didn’t say anything she ll use the blue one, just a litle disapointed
