This is an awesome toy. I have grandkids between the ages of 2 and 14 and they all enjoy playing with this. It is plastic and we have broken a few of the smaller pieces but there were extras included

I've given this toy to several 3-4 year olds over the past few years, and it's always been a big hit, with both boys and girls.The parts are big and colorful, and easily assembled by small fingers, with an occasional bit of adult help at first. The base-plates for the gears fit together like jigsaw puzzle pieces, and the gears themselves can be placed pretty much anywhere on the plates, which allows for literally hundreds (perhaps thousands) of different combinations to be made. Once the gears are placed, a spin of a gear or turn of a crank, and the child's whole display -moves-, to the endless fascination of kids in this age group, and even beyond. My nephew and niece played with this for hours, which at that age, is like an eternity.The great thing is, the kids are learning good basic physics, without even realizing it -- toothed-gear motion; ratios; mechanical advantage, etc. The plastic parts are durable and easily cleaned. The box is fairly heavy-duty and good for storage -- like Legos, you probably don't want to step on any of these gears while barefoot.Overall, this is a great product, from a company which produces a number of innovative and entertaining quasi-science toys for young kids -- Quercetti. I used to be able to buy their products in a local toy store, but as with so many things these days, I was eventually driven to the internet, as they became harder to find locally. Be that as it may, Quercetti products, and Kaleido Gears are well worth seeking out for kids in the 3-6 year old range.Highly recommended.

Our two and a half year old son received this as a Christmas present and loves it. Unlike other reviews, he has no difficulty putting together and taking apart that various parts of the toy. Perhaps we got lucky and got a box that has parts that don't fit together too tightly.There are 16 white "base" pieces that fit together in an unlimited number of configurations. After the user puts all the base pieces together, you can then insert a four-pegged "axle" into the base which in turn will hold one of several different sized gears. The challenge is to lay out the gears so that the teeth of the adjacent gear(s) interlock just enough to spin freely when user turns the initial gear. The layout of the base pieces and the gears are only limited by the user's imagination.With normal play, our son doesn't have any problems with the pieces coming apart or separating from each other as others have commented about in their reviews. When he begins to spin the gears too fast, or gets a little rough with them, then the base or gears begin to separate -- as is to be expected. Also, we've found that working on a hard surface such as a table top or hardwood floor works much better than building the game on a soft surface such as a carpeted floor or sofa cushion.The gears are colorful. Some have stickers, some don't. The stickers have cool patterns that make interesting effects when the gears are rotating. All the pieces are made from plastic durable enough for normal play.After I help him put all the gears together, and before he turns the crank to spin the gears, I'll ask him which direction a specific gear will turn. This makes him think about how the gears are interconnected with each other and the fact that adjacent gears rotate in opposite directions of each other. This is how I turn a fun game into an educational game. When he gets it right, we high-five.If your kids like hands-on games and like creating things, I'm sure they'll love this toy.

Got this as my 2 year old's birthday present, knowing that my 4 year old would also play with it. It can be a tad difficult to make the gears slide in on the base pieces. The base pieces do tend to slide apart from each other with some pressure, it's not like a soild base. But it does add flexibility that I enjoy, and the base parts coming apart isn't really a deal breaker - just push them back together and no harm is done. It is a good gear to base ratio, I tend to have trouble getting ever single gear on the 4x4 base, so it's not like they skimp on the gears. It is fairly trippy to watch. My kids don't play with it as much as I thought they would, but that's not really the fault of the toy. They do like to help me put the pieces on -they usually need help positioning because they like to put them where the gears aren't touching, but I reposition them and then they can push them in on their own. They like to spin it around and around and watch for a few minutes. But this isn't really a toy they can play with independently yet. But we do like playing with it together and I foresee them growing into this toy in a few years. Until then it's still a fun toy for the price, quality, and I think it will last for quite a while.
