My son loves them but they are always in his mouth (he is 17 months). That's my fault. I like for him to play with toys that are for older children. He is pretty advanced. He loves them and has figured our how to align the gears and turn the main gear on/off. The stickers have started to peel off but I don't mind. The magnets are very sturdy and strong

These were a smashing success. Really loved by the 3 year old boy I gave them to and his parents. Provides many moments of fun and wonder. It's really a great toy. The concept is utter genius. It would be nice if Tomy expanded the offerings and kept new ones coming. I can see a whole fridge covered with these! One of the best received toys I've given to my 3 year old friend.

My son (currently 20 months) plays with these every. single. day. He has been doing this for a few weeks. I bought an oil drip pan like this one Lumax LX-1711 Silver 18" x 25" x 1/2" Galvanized Drip Pan, but only $10 at a local automotive supply store, and mounted it on a wall near the kitchen. Our little guy literally wakes up in the morning and goes straight for these. I admittedly didn't put batteries in the motor piece until a couple of weeks ago. I was surprised at how quickly he learned to make the teeth interlock so the gears will turn. He also enjoys moving them 2-by-2 from the drip pan to the fridge, to the dishwasher, and even down the hall to the washing machine. We are super happy with these and if/when they break or get lost, I will definitely order them again. I am only removing a star because the motor gets stuck quite frequently. It's not that big of a deal since we figured out when it happens, turning the motor piece gear slightly will get it going again, but it would be nice if it didn't jam so often. My husband is also not a fan of the piece that is shaped like a short thermometer because it makes a continuous clicking noise (I'm pretty sure it's meant to) when it's in motion.

Pretty good item, HOWEVER please note that the actual item only comes with 5 gears, not the 7 shown.

My son is 4 and autistic. He LOVES things that spin around and are eye catching. Also, he's a nightmare when I'm trying to cook, so I wanted something he could play with in the kitchen and not be tugging on me the whole time. These magnetic gears are perfect! They're darling and well made and he's really enjoyed them so far! However, you should be clear about what you're getting because the advertising isn't very accurate. Here's what you should know:

Pros:
- Magnets are really strong! They stick very firmly without being so firm that the kiddo can't pull them off himself. He is a fridge door slammer and these things stay put on the door when he slams it shut, even when they're turning! I love that. He has also stuck them on the dishwasher door and the oven door (not in use of course) as well.
- Quality construction/durable. My son has dropped these numerous times and they haven't been damaged at all or shown any signs of functional impairment as a result. That's a huge deal for us as my son breaks a lot of toys... Also, the stickers that create the patterns seem very high quality and not something that will start to peel off over time.
- Good battery life! We go through a lot of batteries in our house so it's nice when something lasts a while.
- Gears rotate in either direction depending on which way to push the switch
- Gears included provide a variety of "sights and sounds" to entertain and there is literally no wrong way to set them up which we both LOVE because it virtually eliminates frustration! He can use his creativity and play with them however he wants!

Cons:
- The advertising of these gears in the listing is not entirely accurate which is very disappointing. First, be aware that even though half the pictures show 8 total pieces, you're probably only going to get 6. Look for the pictures that show 6 in a set (main gear, big flower, tiny one with big eyes, small noise maker, medium size one with rotating oblong washer and a medium sized blue face with the wavy eyes that go around). That's the set. If you're hoping for the one with the piece over the eyes that flips back and forth or the one that rotates around different colors like I was, you're going to be disappointed.
- Another aspect of false advertising is that there is no speed control button, at least not on the 6 piece set I received. There is right and left and that's it. Just one speed. It's fine, I just don't like being sold something on false claims.
- My son really loves these and I want to buy more gears (of a different variety) but this is it! I've seen other sets that claim to be compatible with these but all the reviews say they're really cheap and the magnets don't hold at all. That's also disappointing. If you're going to advertise a set of 8 and only send 6, the least you could do is offer additional gears for purchase. Maybe they used to.

Two other things to note that aren't necessarily cons but things to be aware of. The main gear does not turn off automatically after any length of time. It has to be switched off manually. So if my son runs off distracted by something else, I have to switch it off myself. I think it would be great to have an automatic off after 10 minutes but oh well. It's fine. There is a noise maker gear that indeed makes a loud sort of ticking noise that almost sounds like the gears are stuck or something isn't working. Honestly, it doesn't bother me in the least. I know others said the sound really grinds their gears (pun intended) but to me it's the sound of contentment. It's the sound of a little boy who is happily playing by himself and isn't tugging on my arm and whining or head butting my hip over and over again.

In summary, these really are darling, well made, work great and my son loves them. It offers a lot of creativity. I really debated between giving 3 and 4 stars. I hate false advertising in any way. I think it's deceptive and irresponsible of sellers and disappointing/unfair to customers who spend their money. That being said, even though what we got wasn't exactly what was advertised, my son loves them and they really work well and are cute and fun! So, if I'm reviewing the actual product itself, I have to say we like them. Just be aware of what they are and what they aren't! I hope this helps someone else!
