I bought after reading the review on imbikemag.com and I love it.
I use it daily on my Dutch commuter to drop my youngest (3.5 years old) off at nursery. He was previously on a rear set and there wasn't much craic. Now he's up front chatting away and navigating our way through Newcastle. It's made the whole journey a joy. There was initially a little anxiety about having him not strapped in, but that faded after the first ride. He often stands up on the stirrups and I have to watch out that he doesn't catch my chin with his helmet on the way up. Also my over 70 year old dad took him out for a ride with it on his eMTB on some bridleways in the lakes and they had a blast.
It's not cheap, but the build quality justifies the price and it's really easy to fit. While I can only speak of my experience, but my commuter bike (with a single leg stand) is so much more stable when I put my kid on the bike than when he was on the rear seat.
It's a great product and I would recommend to all looking for a more social way to commute with their child.
