What is the functional difference between closed and open domes? Why chose one or the other?

I didn't realize there was a difference. I just ordered the same ones that came with the new aid's. I may try the closed next time if what the Pamela South answer says is true. Good luck! Rodney G.

The closed done lets you get more hearing than the open domes. The open domes are more confortable to me, but with loss of so much hearing, need the closed to get every sound I can get picked up. It does not take long to get used to the closed dome, a copy of days and you are good to go.

There are vents in the top of both gables. They can be cut open and the pieces removed or not. Open or closed your choice.

No. It's like a shell. When it's closed, the (one) mirror is covered because it's on the inside of the shell. When it's open, the side without the mirror folds down and around so the mirror has a stand. It's especially great for travel, when a magnifying mirror can be hard to find.

The dome is made of two parabolic mirrors, one with a hole in the top. They come apart and could be used for other interesting projects.

Having using both with glasses, I would chose the compact. It is rectangular rather than square like the original. Thus you don't have to turn head much to take a look.

Open backs allow for a better listening experience, but others around you can hear what are you listening to. Closed backs feel more confined but offer a more private listening experience.

there is a single flap that opens in both directions. the flap has decent insulation when flap is closed. ours closes completely most times under normal use (lab going in and out). sometimes it doesn't close completely and there is a gap. when we notice a gap, it is easy to close. not a perfect solution but it works well for our purposes in light of the moderate cost and very simple installation/removal that requires no hardware or alternations - easy to drop in and take out. we live in SE Pennsylvania. during major cold spells or if we are going away, we take the whole thing out and close the window. there is a single flap that opens in both directions. the flap has decent insulation when flap is closed. ours closes completely most times under normal use (lab going in and out). sometimes it doesn't close completely and there is a gap. when we notice a gap, it is easy to close. not a perfect solution but it works well for our purposes in light of the moderate cost and very simple installation/removal that requires no hardware or alternations - easy to drop in and take out. we live in SE Pennsylvania. during major cold spells or if we are going away, we take the whole thing out and close... » Read More there is a single flap that opens in both directions. the flap has decent insulation when flap is closed. ours closes completely most times under normal use (lab going in and out). sometimes it doesn't close completely and there is a gap. when we notice a gap, it is easy to close. not a perfect solution but it works well for our purposes in light of the moderate cost and very simple installation/removal that requires no hardware or alternations - easy to drop in and take out. we live in SE Pennsylvania. during major cold spells or if we are going away, we take the whole thing out and close the window. « Show Less

I can't even tell the difference between the two. removal was a pain, because they snap in, and mine domes a bit in the middle, but that's my fault. looks the same, works the same, worth every penny. i had techie friends who told me i was better off ordering a new one than attempting to replace the keys.

I usually leave them open because it can get very hot but I suppose it depends on how much moisture you need for what you are processing. Open lets more steam out, closed keeps the steam contained. For color/ chemical processing I'd say open but maybe for conditioning treatment keep them closed.

The difference is that an open back has mesh or plastic with holes to allow ambient sounds and airflow. These are good for long periods of wear, or where there is a need to hear things other than sound from the headphones. Closed back are completely closed, and usually offer better sound quality and prevent sounds getting in or out. My wife complained when I would wear open back headphones because I would have it turned up enough she could hear the sound bleeding out.

An open door or window is recommended for cross ventilation. Have in mind that the Air Coolers work best in climates where humidity is low.

Hi, in 9 years renting and then buying our own unit, we have never used a dome. Outdoors at parties, the unit has its own table against our house. Floss does fly up and the maker will get it on his/her arm. It's okay !

The dome is for an old model that is discontinued. If you want it you have to buy it in pieces. Good news is you need the base, the pump, and the filters; these actually cost less apart then what the new item went for.

This foam is the "closed-cell" type. Based on my research, closed-cell is preferred over open-cell for below-grade insulation or on floor-joists in a basement or crawlspace because it is much denser than open-cell and is a very good air barrier as well as a water vapor barrier.

There is an inner domed portion (which is mostly flatish on top but definitely domed on the sides). This inner portion with the dome is surrounded by a flat outer portion which has ridges. So both - domed on the inner part and flat on the outer part.

I don't think there is a difference. The oven cooks using convection and infrared technology. I don't know why they list them different. I bought this black one with the extender ring. I love it. It comes with a pan, 2 metal racks, the extender ring and a DVD to show you how to use it. They also give you a plastic coated 8x11 card that is a quick guide to how long to cook meats and a little cook book. Here's my advice to you. They give you this lid holder. Don't use it. I think that is one of the reasons people's domes are cracking. The plastic gets really hot and the heating unit on top is heavy. When I want to check or turn the food, I pause it and completely take the dome off and place it upright on a wooden cutting board. Further more. When your food is done cooking, take the heating unit off the dome and let them cool separately. After the dome is cool, as in after your meal, hand wash it. People seem to have a problem with the dome cracking. I don't. I never put it in the dishwasher and I never leave it on it's side. Other than that, it's a great oven and I highly recommend it.

Open is 8.5" x 6.375", Closed is 3.25" x 6.375". Keep in mind that it is a soft case and you could "scrunch" it up when closing to make it a little narrower if needed.
