We just got this yesterday and assembled it, so I'll come back to update my review if our feelings change after a few months of use. This is currently being used by a 4-month old. Assembly was rather easy EXCEPT FOR putting the seat on. The first strap was easy to get in, but they got increasingly harder to stretch as I worked my way around to all four. I was not prepared for it to be so difficult! I actually had to have my husband come stretch the other straps so I could get #3 and 4 through the hole. It pretty much took as long to get the seat fastened in as it did to get all the rest of the parts assembled. It's very hard, people! But, once it was in, I felt pretty secure about how sturdy it would be with a kid in it. We also have the Fisher Price rainforest jumperoo, so I'll contrast a few things with that. The seat in this jumper sits lower to the floor, but is much more shallow. So, whereas our kids feet can touch the floor in the lowest setting in the jumperoo, they cannot touch in this one even though it sits lower to the floor. They still have about 3-4 inches to go before they can touch in this one! I was surprised by that once we put them in the seat. Nothing a little pillow underneath can't fix, though. The seat being more shallow than in the FP jumperoo also means that they sit in it differently. They tend to lean forward more in the jumperoo and sit back (a little more relaxed, it seems) in this one. I'm not sure that either is better than the other, but just an observation I thought was worth sharing. The other thing that I've noticed is that it seems further for them to reach all the things on this one than on the jumperoo due to the positioning of the seat. They sit back a bit, which means it's further for them to actually reach the toys and piano keys. So, there's that. I like the way the different things attach onto the outer part of the seat. The little sun is a bit lame - I wish the part that holds it up were more flexible so they could reach this to pull it toward them. But, maybe once they get bigger they'll be able to reach to chew on it or something. Also, there are no pictures that show the section with eye hooks. Maybe this is because it's a little lame. They call it a 4-sided play station, but there really are only 3 entertainment areas and this one empty spot. I like that they've included the eye hooks so we can stick other things on there. But, I would have liked to have known this before I bought it... or even as we were assembling it! The eye hooks are packaged in with the hanging music notes and things, just fyi. I read a review that said these parts were missing. But, I'd be willing to bet they just overlooked them because they didn't realize what they were. The seat itself spins nicely, although of course we have to move it for the kids when it's time for a change. Again, something that they'll likely be able to do on their own once they are a bit bigger. In contrast to the rainforest jumperoo, the way the padding fastens into the seat requires that we remove the seat completely in order to take off or put on the padding. Our kids like to do their business when in the upright position, so I can see this being pretty annoying as compared to the slick way that the FP items hook around and button in (if you have a "sit me up" floor seat from FP, their jumperoo uses this same fastening method for the seat itself). All in all, I really like the bright colors and functionality of this jumper. Not all of the stations have things that "do" something. Some are just things to look at or touch. I'd like a couple more lights - our kids love lights. The dangly music notes and duck things are pretty lame. Give me something that at least has a bit of texture or jingle to it! We were able to attach some other small dangling things instead of those (which is probably not recommended, for the record), so that's working out just fine. The kids seem to like the jumper so far. It's a nice alternative to some of their other play things, including the FP jumperoo.
