LO got this as an early Christmas present. DH put it together and he recommends a power screwdriver. He said without that, pushing down the springs while trying to manually tighten the screws would have been a two person job. I would suggest making sure not to over tighten when using the power drill. Set up was pretty quick -- maybe 30-45 minutes? The toys sit in predetermined niches on the play table area and the extra play mat is separate.LO received this when she was about 3.5 months. So far we have used the tummy time mat and the Excersaucer parts. Review on both:* Play Mat & Overhanging Toys - The mat has little bit of padding to it which is nice if you have hard floor surfaces - The bases for the overhanging toys are not so good if your baby is rolling-- they are light weight and move all directions if they are hit. This is true if your baby is strong enough to grab the butterflies and pull. LO did sit under it for a while, but not as interactive as her other two play mat. I would recommend this almost as a travel play mat, but not your primary one-- not entertaining enough. We now use the mat for straight floor play and tummy time. - The design is fun and interesting. LO tries to grab at the animal pattern.* Excersaucer - LO did not like her first sit in the excersaucer. I do not think she understood what to do or how the toys worked. I put it in her play routine to acclimate her to it. After about a week she would grab the dragonfly and try to reach for the butterflies. - It took her another two weeks to learn how to swivel, but for some reason, she only swivels to the left (like Zoolander, lol). But she will probably learn the other way soon. Once she figured out to move, she swiveled around to each little station. - The three level changes are easy to adjust. We had her on the second notch when we got it, but she didn't understand that it was more than just a seat, so we had to lower it. Once we lowered it, she could stand and sit, then move the seat around. She is now on the second level and moves at ease. LO is about 26" and she can stand flat footed on the level 2 notch. - The toys are entertaining enough, but she does get bored with a longer sit. The iguana is motion activated and sometimes will go off if the baby moves too much. I put extra toys in the voids so she has ones she can pick up and put into her mouth. - All the toys have an off switch. Buy batteries. They haven't died yet (one month in), but three of the toys require them. - The globe toy rotates. We didn't know this at first, and LO would hit the same gorilla one over and over and over again. Now we turned the earth, and we get to hear the cat over and over again, lol. - The monkeys are okay. LO has not figured out they can go to the other side. She just likes to hit them on the bottom. One note, I had one of the monkeys at the top, and then forgot. LO started batting at the other monkey at the bottom and the top monkey followed the track and squished her little fingers. It was my fault, but I could see once she learns how to slide them this might become an issue. - The parrot on a tree is one of her favorites to spin, however, when she is facing away from the parrot and sometimes jumps back, it has come close to hitting her in the head. Make sure it is pointed to the sides when not playing with it. - The dragonfly just sits there and she loves it. She bends it almost out of the base to try to get it into her mouth. - The butterflies she cannot reach yet. Maybe when she gets taller. - Make sure to take the cardboard collar off from around the blue bird. We did not know that it squeaked when depressed (we just found out this yesterday after owning it for a month).Overall, I would recommend. I was worried at first since she did not warm up to it all that quickly, but now she happily plays in it for about 20 minutes. LO is still too young for the stand-up part, so I cannot review that.
