Anybody use any of these? [inline water heaters]

I found it funny for 25 bucks they call the Chrome shower head and Stainless steel hose an upgrade to the one that leaks but looking at the L7, it comes with the upgrade... looks like this is going to be the replacement of the L5, maybe the upgraded shower head won't leak?

Thanks for the links mailes. Hopefully mine will last a good long time.
