My twins use this every. Single. Day. It is very well made. It took me a few minutes to figure out how to best adjust the pieces to the various shapes, but I got the hang of it eventually. LoL.
This DOES take up quite a bit of space. So I wouldn't recommend it if you don't have a lot of space.
We got the modifiable pikler with the slide, it arrived in 2 boxes 4 days apart. So if you order the multi set don't panic too soon, the rest of your order may be on it's way, just a few days later.
I found this to be a great quality item. Sturdy wood. I was worried that the individual star shapes wouldn't fit into each other as I adjusted the pikler, but they worked, sometimes with a bit of wiggling.
