-- Vibrating Alarm Module (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=15252)

Due to my work environment, the only "neccessary" module to me is a vibrating alarm. Any one have experience with one of these?

The Innogear module works well and it gives 2 meg extra memory too.

Works great for me. The only module that I keep in at all times. I also benefit from the vibrating alarm, as can not hear the audible alarms from the Visor Deluxe (frequency hearing loss).

So far, the module has been very reliable.

I only have two comments:
1. When the batteries are low the first sign is the vibrate module does not operate.

2. When you are in a quiet environment, the vibrate module is audible enough to be heard by nearby people.
