They're fine but really the 4K video from them isn't any better than the 2K from the Pro 3 cameras. If you're happy to pay a monthly subscription fee, I'd say get the Pro 3. The Ultra also has wind noise reduction but I haven't done a side by side comparison to see how much of a difference that makes. I can't say I have a lot of wind noise issues with other cameras though. I see BestBuy has the Arlo Pro 3 kit with 4 cameras for $649 whereas the Ultra kit with 4 cams is $999
