Yep I have 2 Marineland Stealth heaters and they are great. Shatterproof so it puts your mind at ease. Plus its a darn good heater. It keeps your water within 1 degree of the desired temperature just as advertised. One of my old glass heaters was set to 76, but didn't shut off until the water was almost 90 =/
Also for people who are still using glass heaters, I suggest using a Surge Protector and hooking up all your aquarium equiptment to it so when you go to do a water change, you flip the switch to shut off the power to your filter and your heater will go off with it.
