Great for commuting with my ebike
Works well for an electric bike. It's fairly heavy so I would not want to carry it around on a road bike. However, it feels solid and I don't really notice the weight when I have it in my ebike's panniers. I recommend getting a Velcro strap to wrap around the chain so it doesn't flop around in your bag. The fabric sleeve around the chain is soft and I haven't felt any concerns about it scratching my frame.

It's a beast, super high quality and heavy-duty
This thing is a BEAST. Really high quality, I can't imagine anyone getting through this thing. It was actually more than I bargained for; but that was my fault for not reading the specs where it says it weighs 7 pounds. I returned it and got a smaller size, but that's all my fault and no reflection on the quality of the chain. Great if you're looking for a high quality, super-heavy-duty chain!
