Excellent drill. Well used for over 3 years, it has done it job and done it well. While I have not yet had a problem with the keeper loop coming loose, that area does catch my eye as a potential problem. There is a groove that is cut into the rear of the handle and here a simple wire loop with a swage which is wrapped around this groove. To the naked eye it appears this loop could easily come out of the groove and your drill would be lost. But experience has proved otherwise, I have not lost the drill and nor has my partner, who has had his for 9+ years. My one improvement would be a more confidence inspiring keeper attachment.

I've never used the Rocpec so I can't compair the two.
The Pika can get the job done. One drawback I've noticed is the the keeper cable may loosen up and come off.
