Product review (4 stars): Nice cooktop!
4 to 5 stars. The gas connection is sturdy if connecting a straight line connection. But when using an elbow, there's too much torque at the bend, which can ratchet around the fitting, loosening the connection. I think repeated expansion/contraction cycling from heating/cooling at this junction will loosen the connection over time. Mine leaked from the start, ("professionally" installed by gas company because I needed the permit and record to comply with state law and for insurance; I didn't even bother calling them back, instead doing the work the right way myself). When moving the flexible gas line slightly a few times while securing it underneath, this movement was enough to loosen the elbow, even after tightening the connection tightly. I built a bracket to hold the entire elbow and gas line in one place, with everything tightened up. No leaks and very secure underneath. Up top at the countertop,  the closed foam strips used under the cooktop edges, at countertop, are good for padding. Over time, liquids could soak into the foam stripping, leaving bacteria. So, after securing the cooktop in place, I added a small bead of silicone seal all around the cooktop, to keep liquids from seeping under it and into the closed foam seal. Nice cooktop, heats food with very little waste heat. For lighting burners, the approx. 4 seconds holding down control knob while safety components heat up is easy once I got used to it. Most gas ignition systems have this wait nowadays, for flame out safety protection. Both burners needed adjustment to lower the flame levels at lowest setting. An adjustment screw for this is inside the stem of each control pod. After pulling the knob up and off, the small access hole is right at the top of the stem. You will need a long thin flat head screwdriver to insert down the shaft to the screw. you can  see the small screw head down there if you shine a small flashlight light point and use a magnifying glass to look. Remember position of screw, then insert screwdriver  oriented same direction and connect with screw. You will feel the fit when screwdriver is seated. Turning clockwise reduces flame size, counterclockwise increases it. Don't push down hard as you turn screw, as this will reduce flame size temporarily until you release pressure. For a screwdriver, I bought a Master Mechanic 3/32 screwdriver at True Value Hardware, and ground down the screwdriver shank until it fit easily into the control stem hole. Shank should be 2 inches long to reach bottom. EXCELLENT customer service. I emailed asking if the cooktop can be lit with a match or lighter, if power outage (Yes, you can light it with a match when power is out).  Emailed on a Friday late. Next day, Saturday, a rep. called me at home and left a detailed explanation message, gave his direct line phone number to call with any further questions. I'm very happy with this cooktop and the company.
