Thought I would jump in and give a little clarfication on UL, CE, ect.
1st off let me get this out: These logos do not have anything to do with quality.
These are safety logos. As someone has mentioned before they are tested by a 3rd party laboratory. In order to get the UL mark the lab has to be recognized by UL. The lab will test to the appropriate standard UL60065, for example. This is for Audio/Video equipment. There is also CSA, ETL, ect. These logos mean the product will fail safe. In other words, there should be little risk of electrical shock/fire/burns/ect. Terms like creepage and clearance and double insulated wiring is used to help prevent this along with flame rated plastics (V-0 for example), among others.
If a product does not have a logo it does not mean it was not engineered to be safe. It means the vendor did not send off for the 3rd party verification as it is quite expensive. Granted the testing can be stringent, but again, has nothing to do with quality. In fact, it's normal for the product to not work after the testing because it is simply being tested to be safe at failure.
It's also good to know the UL (or CSA, ETL, ect) logos are for the USA and Canada only. cUL is for UL Canada, ULus is for UL USA, and cULus is for Canada and USA.
Different countries have different requirements regarding safety requirements, therefore for different countries different testing has to be done, ect.
The CE logo is for Europe only, it has nothing to do with or required for the US or Canada. So whoever said it was a higher listing than the "UL" logo is full of it. In fact, the CE logo is a self declared logo. This can be put on a product and it never tested. However, if EU authorities were to request the documentation proving worthy of the CE logo the vendor would be required to produce it in a short amount of time. While the EU is a 230V area, many 120V products have the CE logo on it as well. This is simply for marking sake and to help keep vendor skus down. Makes it easy to just have the CE logo on everything.
Anyway, just thought I would shed a quick bit of light on the logo subject. To each their own if they elect to not purchase because it doesn't have a logo, but does not mean the product won't fail safe even though. ALTHOUGH..if proper engineering practices weren't used..it surely could, but here is the US that's dangerous with how sue happy we are.
Also worth noting, just because it DOES have a logo, doesn't mean there is NO risk in injury, fire, ect. Another bit of fuel on the fire, a lot of the time the testing is done in China. Sad to say, but there are times when money talks..so a logo can be "bought" and a report produced showing it met, but in actuality..it doesn't. So the logo really can lose it's meaning fast with that knowledge.
What I'm getting at mostly is don't be too weary just because the logos are missing. Look the product over and if it looks unsafe...it prob is. I am a compliance engineer and own the GG6", I've looked it over..I don't see any issues with it BUT don't plug it in, stand in a bathtub full of water and drop it in and say "watch this..it has a logo on it!"
