Do you use X items?

I don't. I usually sell them all at the Pokemon League to buy Max Revives and such.

Also, if there is already a thread like this feel free to close this.

Heck no, they bring no use to your Pokemon's benefits once you outlevel your opponents.

No, X Items are just money to me

Nope. I never have used a X item. They are useless to me, well, I do sell them.

Nope, never have. I feel like using them is a wasted turn.

No. They seem useless. They're only good for selling.

Nope. They don't really seem all that useful in a battle and it seems more like it's wasting a turn to use the item. I usually either keep them or sell them if I really need the money buy the more expensive items like Max Revive and Full Restore.

Nope, I never use X items. You have to waste a turn and they aren't that great in my opinion. I either just keep them or toss them.

I never use them. I sell them whenever I get one. Seriously, the turn you use the X item you could just use something like swords dance instead.

No X') They're so useless... I only sell them for a few extra money.

I only used them once on my Excadrill while I was facing Cynthia in Black to increase its speed because it was underleveled... otherwise no.

I won a battle thanks to them.

Basically I was poison-stalling Bugsy's Scyther with a low-level Chikorita. It got to one turn to live, but Reflect wore off and Chikorita wouldn't survive the next Fury Cutter without it.
So I used an X-Defense and it actually worked.

Now I always carry them and try to do unusual set-ups.

Nope. I normally just sell them.

I did use them once though, when I was battling Wattson in my Normal monotype Ruby run. I used X Attack on my Loudred to make it easier to take down his Magneton.

Definitely not. Using them feels like wasting a turn to me.

They don't ever seen to come in handy, so no.
