GuidecraftRainbow Blocks - Shimmering Water: Creative Colorful Learning and Educational, Construction Building Toys Set for Kids - Stacking Blocks

I have been buying block sets for my oldest grandson (6) for a couple of years now. He has the plain and colored water filled sets and now the sand ones. He is so creative and has so much fun building. These blocks are durable and teach shapes, and colors. Open ended and easily transformed into many things they are a great toy.

I saw these and just a good feeling about them-was hoping they'd be worth the price, after all, there is only 8 blocks in each set..and they were! They are balanced, sturdy, attractive, but best of all, they appeal to our autistic young daughter- they command her attention and concentration as she stacks and build with them, and engages with these for longer than foam or small wooden painted blocks. I really, really like these and still may buy a second set! :)

I bought the sand, water and bead blocks for my one year old granddaughter. She loves them! She looks through them, shakes them and is just starting to stack them. They are of very good quality so are very durable. The also do well when added to other quality wood block sets.2011 Update: Two years later and these blocks are still enjoyed by granddaughter (now 3 yrs old). The water filled ones are still clear, not cloudy, and still no leaks which happens with some cheaper sets. Still give them a 5-star!

My 15-month old loves these, even though he doesn’t really build with them yet. The water is colored and sparkly, and he’s dropped them many times with no damage to the blocks. I love that you can hold them up to the sun and learn about color mixing.

i have ordered two sets of these blocks. I gave one set to my daughter for her first birthday. She loves them, but one of them cracked and leaked some fluid. They are still nice, but that was disappointing. She didn't have them long at all before that happened.I recently ordered the second set as a birthday gift for a cousin's daughter (I forgot about the cracking issue and other than that they are great blocks).. And at least one of the blocks arrived cracked already!The blocks do not come padded in any way in the manufacture's box.. Maybe that is the issue..? I can't say when or how exactly this is happening, but the manufacturer needs to give it some consideration. Awesome toy otherwise, though. I'm a Guidecraft fan.

My little loves the colors and building with them. Perfect addition to our open play! Sometimes they look foggy, like a windshield, from the inside which means maybe air is getting inside somehow. So at some point I’m sure they will be leaking. Hopefully not. We loves these.

The quality is fantastic. The wood is smooth to touch.. and blocks have a nice weight to them. The only reason I'm docking a star is because the sand sticks to the inside of the plastic.. it's not like how it's pictured.. I think if they used a less fine sand it would look better but that's just me. You can still see through the non-sand part especially when held to light. It makes a beautiful sound when the sand shifts so I am sure my children will enjoy it.

These blocks are so pretty to look at and my 2 yr old grandson loved them. He was on the floor playing with them and the sun was shining in and they were just shimmering in his tiny hands. Easy to stack!
