First of all, if you are at all on the fence about buying a bidet, go for it. I strongly recommend it! I really miss mine when I am not at home. It has become the kind of convenience that I never want to have to live without. A friend used it and said, "Wow, that is a game changer." I own both this bidet, and the Brondell s1000, that I bought a few years ago. I really like the Brondell brand (although to be fair, I haven't tried any others), in large part because the toilet seat, when closed, can be sat on. (The website says the weight limit of the L99 toilet lid is 160 pounds. The weight limit of the Swash lid is 270 pounds. They look the same to me, but what do I know. Go with what the manual says. The weight limit of the seat when open - e.g. not the lid - is 330 pounds.) I never actually sit on my closed toilet seat, but I used to do it all the time when my kids were small (supervising them in the bathroom), and it's nice to know that a) if I wanted to I could, and b) I don't have to worry that other people who use my bathroom might sit on a closed toilet seat and break it. This model was not available when I bought my Swash 1000. To be honest, I like the Swash 1000 better. But it is also more that twice the price of this model, and the things that are better about it are not worth that much to me. I would rather buy two of this one, and I would be perfectly satisfied and even have a little money left over. I think the heater is better on the Swash 1000. My impression is that the warm water is more consistent. I suspect that I could run it all day and the water would be the same temperature all the time. With the L99, there is a slight variability in water temperature. Nothing that is problematic, but I think the heater on the other model is probably better. I also like the remote better on the S1000. The buttons are somewhat raised, and it is just a little bit less sensitive, so you only "turn it on" when you really mean to. I have changed seat temperature and water temp on this one just by brushing up against the remote. (The water doesn't turn on unless you are sitting on the seat, so that is not an issue on either model.) Again, not a deal breaker, and certainly not worth over $300, but still something worth noticing. Finally, the s1000 sounds quieter and smoother when it is operating. The L99 makes a somewhat startling sound when it starts up. The seat is very comfortable. I really like that the seat is heated. The water temp is comfortable. (Warm water makes a difference. I have tried both, and definitely prefer using warm water.) I didn't care one way or another about the night light when making the purchase (the s1000 doesn't have one), but I like it. I like that the nozzle is stainless steel. That may be my imagination but it just feels more sterile than a plastic nozzle. I really like that the nozzle is self-cleaning. The bidet was easy to install, even with modifications that I had to make because I have a skirted toilet. It's a little more work to clean than a regular toilet seat, because you have to pop the whole seat off the mounting plate that it sits on to clean underneath it, but again, not hard to do and certainly not a deal breaker. (You have to do that for both models.) Overall, this is a well priced bidet with a lot of high quality features. Highly recommended.
