Oxford Screamer XA7 Alarm Disc Lock

Within the epic battle of predator versus prey, it's better to expect an attack than to be caught off-guard.

Here, a common encounter unfolds:

An Oxfordae Screamerus watches over its single brood with a wary vengeance. Nocturnal by nature, the XA7 frequently extends its fervent diligence into the daylight, sitting anxiously, rabid as a raccoon. Perched upon its chosen rotor, it waits, talons clenched. A Totalus Pieceofshitacus approaches. Armed with bad intentions, devoid of developed frontal lobes, the lurching menace waters over the XA7's chosen habitat. Driven by cowardice, the Neanderthal initiates an attempt to drag its victim to more convenient location to assure its demise. Poised with enough potential energy to kill a horse, the XA7 unleashes its full counterattack. A full 100dB surges towards its attacker's senses, causing disorientation and an acute flight instinct.

The XA7 Screamer certainly packs some serious attack-thwarting firepower, but also possesses a tenacious steel shell with a 7mm hardened steel locking pin, should things get escalated to blunt force trauma.

It's OK
This review will be 2 fold - one part on the lock the other on the odd experience with RevZilla.

First - the item was stated as "Available - Ship within 24 hours" Apparently this means it drop ships from somewhere else. By day 3 I had no tracking and called RevZilla. Trevor helped figured out what was up (Thanks!!) - it apparently shipped but at some point no one scanned the package. I finally got tracking info about 2 hours before it arrived. Strange & Odd. Was it terrible? No but I prefer to keep an eye on my packages to ensure it doesn't walk off my porch.

Product: It's OK, nothing fancy. Instructions suck! They are small and might require some to get a magnifying glass out.

Pro Tip: the battery has a very tightly wrapped semi hard plastic all the way around it. I guess I'm blind cause I missed it..... thought the battery was dead and was ready to go get a new one when I realized I missed this wrapping. Don't miss the wrapping! The instructions say nothing about removing this...... Did I mention the instructions suck?

I placed it on the disc and hit the button to arm and it beeps...... to let me know it's armed. I wiggle it and nothing happens..... I rearm and leave it alone. Come back later and wiggle it and it beeps 3 or 4 times and does not go off..... OK it needs more for it to trigger. I kick it and jostle it. It goes off! Great! It works! It's not sensitive. I'm ok with that.

In short: It's OK once you figure it out.

I like Revzilla and will order again. Just in case you were wondering.
