Hi Yan,
I had this playzone for my little one back in the States and we loved it for our needs. Our little one was rolling around at 3 1/2 months and we had 2 crazy cats, so it was peace of mind for us as the cats did not want to have anything to do with the playpen. He loved looking at the toys and when he got old enough, started playing with them alot.
That being said, we did buy 2 additional 'wall' sections for the pen since the 4 that it comes with is really not much more than the size of a pack 'n' play pen. My one gripe was the gate which was pretty hard to open and close, so we just hopped over the pen each time. (with 2 extra extensions, both mom and dad can fit with baby inside.)
After he out grew the pen (about 1 year old, we took apart the sections and placed them around the house to block him from getting to all the electronics and fireplace.
I haven't seen it out here in HK yet, but if I see it, I'll let you know.
