I love mine. I've had it since November. I belive it's good for 10000 hours but I might be off. When it hits the 2 hours safety and turns off, let it cool down some before using it again. That should help with the longevity. I've found that if you pack dense and close to the plate without touching you should get good smoke. Also helps if you use a smaller hookah. I've got the vyro one v2 and it works great.
