I bought the glass top and it was delivered in 2 days! I watched one youtube video on how to remove and reattach the new one. Literally took 15 minutes from start to finish. You turn off the electricity to the stove top, pull the whole unit up and set it on the counter. Unscrew 10 or so screws around the top. Then just pull the broken top straight off and replace it. Then put screws back in, set it in the counter and turn the power back on. Extremely easy. If you can lift 60 to 75 pounds or team lift it, you do not need to pay anyone to do this for you!
