The kids love these, seeing the different colors through the lense.

I will be using these color viewers in my reading centers. My students are going to love these tools.

These are great for little ones. They love the sensory fun.

These will be lots of fun for my 2 year old class. My grandsons love them.

My son is so intrigued by this magic!

Great color viewers! My one year old has a lot of fun with them.

I agree with other reviews that they are difficult to clean. We learned the hard way that they can't be submerged because water will get in and fog up the lenses as others have already said. So after we figured that out, we washed them by hand and stood them handle up to air dry. 1 yr olds loved them even if they're scratched. They are durable and stood up to 10 crazy 1 yr olds for over a 8 month time frame. That's hard to do for a hand held toy such as these.

I really like the design of this product as far as safety is concerned, however I would like them to produce a more transparent color plate to look through. It is difficult for our toddler to see through and i think it would be so much fun for her to explore color combinations by overlapping the color viewers.

I bought these for my library's baby storytime toy box. Cleaning the the viewers left a sort of spotty residue on them. I've scrubbed them several times with different products, but cannot get the residue off. Very disappointing!

I have found that while the handle and lens of these viewers are very durable, we have had several that have gotten scratched or have fogged up after being washed. Working with young toddlers, items such as this often get put into mouths (like any other toy) so they need be thouroughly sanitized. Ours did not fair will after one sanitation, and they are now difficult to see through. The children continue to play with them, however, and love to see what color their world becomes when the look through them.

So far, these have been very durable and I feel comfortable letting my toddler and preschooler play with them. They are easy for little hands to hold and use.

My SDC 1-2 students love using these! They are perfect for activities with the word wall. The kids also loved putting one on top of the other to see what colors they could make. I am very glad I purchased these and would recommend them to my teacher friends.
