How do you like your "tankless" water heaters? - tankless hybrid ontario

I look forward to our time with a replacement from them. Far from what I've read, seems to be the way forward, but I do not know who has personal experience with them. ASO I know they are at the upper limit of what the cost, but also as hybrid cars, it seems that you save on energy costs over time, is not it? I would appreciate your comments to know that I thank you for or against the current owners!
