I’ve had one as my main bike for over a year. I’m not sure what your needs are but here are my thoughts:

• It’s generally well suited for everyday city life. I rode mine through the winter and never washed it. The belt doesnt care.
• The gear range is great unless you have steep hills.
• Weirdly, the fork doesn’t have the mounting hole at the bottom for a fender, but it does have one at the top. I use their recommended fenders with the Velcro straps and they’ve been great.
• Be sure to practice taking the wheels off. The gear cable attaches at the back in a weird way and you have to disconnect that to take the wheel off. Make sure you know how to do it.
• The hub really doesn’t want you to peddle while you shift. If you do, it will feel like you shifted just fine and then a few seconds later your drivetrain will jolt as it actually gets into where it’s supposed it.
• They say you can’t use a front rack but it has all the mounting points for one. I suspect this is because tightening a bolt too hard on the carbon fork crown could cause safety issues. I have a rack there anyway and it’s been fine.
• The hub has a sprag clutch which means it doesn’t click. It’s truly silent while pedaling and coasting.
• The rear sprocket is a Gates Surefit. This requires a special tool to take on and off. I had to buy one off Italian eBay. Your bike shop almost certainly won’t have one.
• The bike is pretty heavy. Not that big a deal for most things but it is what it is.
• I’ve changed the oil once but otherwise never messed with the drivetrain. It’s very low maintenance
