I got the F1 ultra a few weeks ago it is awesome and now the cover is sticking and hard to pull all the way up. Slides nice half way up but the other half is sticky jerking and just feels bad and wrong. 

So my question is can I oil or grease the slide so it moves smooth or box it ship it back and get a new one?

I figured the slide cover would last longer then 2.5 weeks of smoth operation. 

Its all new with the whole package, rollers and conveyers. 

I love any feed back.
