It is difficult to find the perfect cover for fone, pod, pad.
These items are soft, pliant, squishy. They are fairly thick, chubby.
The fit you would describe as good, not perfect. (This is for ipodtouch 4G.) It is a little loose. Do not expect a really tight "snap on" grip at the sides.
The price is so low it is well worth buying one or two to see if you like them. Tecknet ships promptly and actually have stock unlike others.
In the packet I got, they did supply TWO of the screen protectors, which is great. It is the "remove A, remove B" type screen protector which is the only type you want. (They only cost a few pennies so it is good they throw in two.) It usually takes you a couple of attempts to get it on perfectly so it's good they include a couple of them.
TIP, line-up the tiny front camera hole first when applying the screen protector.
These simple products change slightly from time to time so you never know precisely what you will get. For example, FTR the one I got had "press through buttons" rather than "holes cut out" for the three relevant buttons as shown in the photo here. (Obviously there are holes cut out for the plugs and for the rear main camera.)
If you particularly want protection from dropping it, these thick silicone covers are perhaps best - your ipod becomes almost a superball !
Again the price is so low you will have to buy a few different ones to find what you like exactly. Hope it helps! Nobody bothers reviewing these cheap items so, add a review of whatever you buy! Amazon's computer does not understand how to aggregate the reviews from items that are the same in different colours so that doesn't help either. :-/
