Strength:

Nothing good to say about the product or the customer service.

Weakness:

This component broke in half on a green trail with no crash, no hard impact, etc. It is ridden by a 65 year old woman who only weighs 105 lbs. That's bad enough as it should have failed like that. To make matters worse, SRAM refused to honor the warranty, as they felt the mounting bracket should have broken first. Bad product, pathetic customer service.

Reliability for the price

Weakness:

none

Came stock on my Hardrock. Rode it hard for 1500 miles and--while it's not the smoothest shifting derailleur I've used--it was 100% reliable. I kept figuring I'd run it till it broke and replace it with a Shimano something or other, but the doggone thing never even came out of adjustment, much less broke!!!

Strength:

it looks good, shifts good and hasnt given me any bother in 6 months of raking the sh*t out of it. cheap.

Weakness:

a bit floppy, the chain hasnt got much tension, gathers mud easily and gets squeaky after that. (washing it thouroughly stops that)

i have it on my freeride bike and rake the balls of it and its running absolutely excellent! im very suprised at this because it has lasted longer than my shimano deore's that i had. id get it coz its cheap and has turned out to be very durable.

Strength:

smooth quick shifts

Weakness:

adjustment screw threads will strip out, they use a plastic insert for the threads, i removed mine and taped the hole using a 1/4x20 tap and use a bolt for the adjusting screw.

i would buy it for cross country riding, if you do any jumps upgrade.

Strength:

strong & quiet

Weakness:

probably not too great for serious shifting

Bought this derailuer knowing I wasn't going to "shred" trails the way I used to, but wanted the SRAM quality... so far, it's been worth it. Shifts nice & quiet without any issues on the flat, up & down hills, over decently technical terrain and even chewed up a finger-sized stick and spat it out without so much as a hiccup.
Def worth the price if you're looking for a good, strong, reliable derailuer and you're not planning on racing or doing double diamond track on a regular basis. 5 flamin' turdies from me!!

Strength:

Looks good, shifts okay.

Weakness:

No barrell adjuster on the derailleur itself, weak spring, goes out of adjustment fast.

This is a good entry level derailleur, that will show its user proper maintanence because it requires it more than others.

It does do its job, and its not very expensive.

Strength:

works as good as x5, x7
the x4 and x5 are stronger than the x7 due to the all steel "gear cage" thing, but not really that significant as far as performance. all have aluminum knucles that break easily

Weakness:

any aluminum part breakes easily

The differances between the x4, x5, and x7 are nothing to brag about. The x4 works great when properly adusted and I could not tell the difference between any of them. They all break at any aluminum part, from sticks in my case, and none of them have replacable parts, except for bearing/gears which don't really break. The part that will break on these is the aluminum knucle that bolts onto the replacable derailer hanger. The differance between the x4 and the x5 is that the x4 has one plastic bearing and one metal, while the x5 and x7 have two metal bearings and the x5 and x7 have an extra part for chain/cog height adjustment, all of them seem to have a very subtle design change. I give it a 4 beacuse it broke, the third I've brook this season so I like'em cheap but I would like sram to come up with a design that doesn't catch sticks as well as these(x4, x5, x7, probobly x9 and x10 since the designs are near identical, all have the aluminum knucle)
