Product review (1 stars): Horrible Oven tray design is third degree burn waiting to happen
Oven racks are dangerous and ignition can take 30s of holding the knob down.

1. Who thinks designing a flip UP lip on an oven rack is a good idea? Hmm? You cannot slide a cookie sheet in (nor out) and if you have something of heft, you will need to put your arms entirely too far into the oven to put the cookie sheet or roasting pan down. It is such a HORRIBLE design flaw that the oven does not deserve to be in any kitchen. Even well trained adults will have trouble with this. What seemed like a strange irritation has become a personal hazard.

The designer clearly does not cook. Or even know how.

2. The other strange irritation is with the gas ignition. The burners finally start in a reasonable time, but they needed several warm-up days before they started working correctly, which brings me to the oven . . . again. The first few times I used the oven I waited until I heard the telltale sign that gas and fire were alive in the oven; I left to allow the oven to preheat, and I returned to the oven 15 minutes later to discover it lukewarm. It was in attempting to use the broiler that I realized I have to hold in the broil (aka bake) knob for at least 30 seconds in order to get the oven to keep the fire going. Fire will start but it peters out if not depressed for 30s+.

I'd consider gas company issues if the burners were still trouble, but the burners seem fine.

One star because the oven sheets really are a very serious burn accident waiting to happen. They should be recalled.

Update 6/7/2014
A reasonable question: are the oven racks installed correctly?
Before I wrote the review I had turned, flipped and tested the oven racks in every conceivable configuration - should have mentioned that in the original review. I ended up going back to the way they were installed when I moved in. Here's why:

When you look at the side of an oven rack you should see a divot. That divot stops the forward motion of the oven rack should you need to slide the oven rack out to remove something particularly heavy/sploshy, etc.

Both lips up: the divot stops the forward movement of the rack without changing angle - in other words, it holds steady. So while you have to be crazy careful lifting items vertically off the rack, at least it won't send the item careening toward the floor when you pull the rack forward.

Both lips down: The divot stops the forward movement of the rack and very unpleasantly changes angle. This means your lamb roast will come sliding at you. Catch!

Based on the welding seams and the divot, I put the oven racks back the way they were installed when I moved into the apartment. Were they installed according to directions? I don't know. The contractors did not leave those behind and I had no problem testing different configurations. A reasonable person should be able to figure out the installation of the oven racks.

The point is - you can do better when it comes to buying ovens. The ignition is still a problem 13 months after installation - it takes at least 22 seconds depressing the bake/broil button for the oven to stay ignited (ignites immediately but will extinguish when you let go of the knob "prematurely"). The oven racks are a hot mess, and it just isn't functional/stylish/cool enough to overcome its flaws.
