We just purchased the ST03 Pro model. When we opened the box we were pleasantly surprised at the level of quality and how well it was put together. With all the functions packed into one package, it gave us quite a good value for money compared to all the other ones we researched.
Pros:
Great look and feel. Feels solid and well put together.
The heated seat warms up quickly! No more cold cheeks on the lid during winters.
Auto open and close works pretty well, the roller mechanism feels pretty sturdy and not flimsy at all.
Water pressure from the pump was strong enough to flush waste away with ease.
The bidet worked quite well with ample pressure, the water was warm right away. It even has water massage settings which was surprisingly comfortable.
The instructions manual is very useful and clear， remote it came with made playing with the different settings super easy.

Not really cons, but room for improvement:
Maybe integrate the functions into an app instead of a remote? 
The entire installation process is easy, but the toilet itself is a bit heavy.
All in all, this is a great and well-designed product, works extremely well and definitely well worth the price.

I've been looking for a smart toilet for several days now, and after a lot of research, I finally decided on the Uncle Brown luxury smart toilet. It's cost-effective, functional, has great performance, and is packed with features. It's also easy to use and has a modern, stylish look.

My kids, my parents, and I all love this toilet! I would highly recommend it to anyone looking for a smart toilet. Just buy it!

If you have any questions about the toilet, the seller's customer service is very responsive and simply awesome!"

So far, we're loving this! Great looking toilet. Nice features. Love the temp for the seat. Lights at night. W

The toilet works as advertised but the unit leaked water onto the floor, in the back, when the bidet was used. The leak was not in the hoses but inside the plastic enclosure where it is not serviceable. Working with Amazon on a fix that does not require removing the unit. Hoping that the vendor will send just the top section that is leaking. A customer service website or phone number would have been extremely helpful.
UPDATE: Amazon is sending a replacement that I can harvest the part from and return. Hoping that the new unit does not leak.

Update:
Amazon sent a replacement toilet that worked flawlessly. The company contacted us, through Amazon, to work out details to resolve the problem. I am very happy with the finished product and will purchase more.

This toilet is great. The quality seems really good for the price. I've had it installed a few weeks with no issues or complaints. The install was pretty straightforward, (be warned, this toilet is just as heavy as a tanked one) but we did need a couple additional parts. Primarily, we needed an adapter for the main water line T connector. (The brass fitting shown in the photo) It had a non-standard thread size, and it was hard to find at the local store. Make sure you check this before attempting install. Also, the wax ring provided wasn't thick enough for the toilet to seal properly, but that's probably due to the fact that my drain flange was a bit below floor level.

Overall, I'm very happy with it. Great value for the price.
