what does class 2, class 4 mean?

The higher the class number the faster it is, and cost will probably show that. For normal Mp3 songs or normal pictures, a lower class is just fine.

I do not know exactly since I never looked it up, but I think it has to do something with the speed of the memory chip.

It's what I used for halogen pendents. Works great. Not sure what the class designation refers to.

class means how fast the memory card reads/writes. The fastest class is class 10 (obviously the most expensive too). You can check this webpage for more information if you are curious.http://www.pcmag.com/article2/0,2817,2388408,00.asp

This hitch should work with a class 1,2, or 3, 2" hitch only. It is solid as stone but be warned, this baby is heavy. You won't want to take it on and off daily.

Class 4 is good enough. I use a class 4, 8G sandisk SD. The result is very satisfied.

i'm using a class four since it's what I have on hand and no problems at all to report.

Sorry, but I don't remember very well because I didn't have that device. Maybe class 4.

It IS Class 4. Slow, cheap, and reliable. I use it for computer back-up, not for photography or video .... where I want a high speed card.

I really don't know. I have always used 4 and never thought about using 2. I don't know why you could use just 2 though.

2x5x2 means they have 2 layers on either side and 5 layers in middle same goes for the other numbers I think :)

Hello John, Unlike card write speeds that measure maximum performance, class ratings measure the minimum sustained speed required for recording an even rate of video onto the card. The class rating number corresponds to the transfer rate measured in megabytes per second. Class 2 cards are designed for a minimum sustained transfer rate of 2 megabytes per second, while Class 10 cards are designed for a minimum sustained transfer rate of 10MB.

Like I said, just making sure. I found a good deal on an 8GB class 4, I think $12.50. Really, not much more expensive than class 2, so I figured: why not?

It depends on which one you order. I ordered 2 inch, 3 inch and 4 inch. It should say it in the description.

4 cycle mean every time the crankshaft moves the piston up and down there are 4 cycles called 1) intake 2) compression 3) ignition 4) exhaust. Also it almost always means that the gas and oil are not mixed together as in 2 cycle engines. There are separate areas for fuel and oil. I would HIGHLY recommend this model because it creates "clean" electricity that will not damage sensitive electronics like televisions, computers, and most other devices containing circuit boards. Most generators do NOT deliver a clean sine wave of electricity.

From what I could find out, the higher the class the faster it can down load a picture to the card. Class 4 is 4 Mbps. Class 6 is 6 Mbps, and Class 10 is 10 Mbps

System 2 is for thinning hair that is NOT chemically treated (i.e., hair color, or perm) and System 4 is for thinning hair that IS chemically treated.
