Query: Not reliable

The problem with the new GRP99 is reliability. It just doesn't last. I bought this unit in Christmas. It worked well until early March and the electronics went dead. The unit would not power up. Getting a replacement took 6-7 weeks. I used the new unit only a few times, and the same thing happened again. No power, no lights, dead.The grill works well while functioning, but it is just not reliable as a home appliance. The company does not provide a partial refund. I am getting a second replacement, and will update my review in a couple of months. The customer rep is assuring me the problems are taken care of. Will see, but not hopeful.
