Please take a look at our Editors' Choice award-winning cams, the Black Diamond Camalot and Black Diamond Camalot X4 to consider as alternatives. You might also want to take a look at the winner of our Best Buy award the Metolius Master Cam.

"Cams Start at 36.95"
This statement, taken from Rock Empire's website, could stop a trad climber's heart and simultaneously empty his wallet (they're so cheap, I can afford more!).
Rock Empire's Robot Cams are some of the cheapest cams on the market making it possible to outfit yourself with a full rack of cams at a fraction of the cost of some of the other brands that we tested. They are rated at 15kn across the board (excepting the Microrobots) and cover a range of .79"-.6" Unfortunately the old adage "you get what you pay for" seems to hold true for these cams and while they perform moderately, there are much better options out there if you are willing to spend just a little more. We found the cams to be both durable and solidly constructed, but rather poorly designed and somewhat nerve racking to have below you in all but the most solid straightforward placements. The cams lobes are rather close together giving the Robots tendency to walk, and while the cams feature and extendable sling it is generally not long enough to eliminate the need for quickdraws or alpine draws to extend your placement. If you are on a super strict budget and are in need of some gear now the Robot Cams will complement the other cams that you have on your rack just be sure to place them well and sling them long to avoid walking. Overall we prefer the stability and performance of the Black Diamond Camalot. For a similar design but superior performance check out Metolius Ultralight Powercam or Metolius Super Cam.
