Product review (5 stars): Very happy with purchase
Received it today and installed it. Looks great and works great so far. Easy install as we removed an 11 year old GE cooktop of the same size. No sticky goo required. Cleaned old stuff off of counter cutout and installed this top which has its own seal, very slick and neat. The grates are very heavy. I couldn't lift them easily but my husband could. He installed it in about an hour with a minimum of help from me but he has done this several times in the past.  The packaging was very secure, no knicks or dings possible. The delivery brought package into house and placed it on the table for us but they do not unpack as stated on Amazon. He did stay while we unpacked quickly at our request. Next day- used the griddle for pancakes after seasoning it per directions. Griddle works great so I think i'll leave it in place. Tri-flame unit cooks very evenly and fast. Like using this cook top. The lock gives a loud alarm if it is on and someone tries to turn the gas on. Very good feature if young kids are around.
