Number 1, Your front door key lock is excellent, if I'm in the house and am unable to answer the door, this just saved me the costly expense of a new window or door replacement. Number 2. The soft but tough wrist sending device is comfortable to wear, & easy to reach if needed. Number3. The belt loops, on the voice activated mobile unit needs wider belt loops. Unless I wear narrow trouser belts it will not my standard 1 1/2 IN wide belt pass through the loops. I have lost the unit in chairs and car seats more than once, so now do not wear it when outside working. Number 4. I appreciate your procedure for checking your system on a monthly basis. It makes both the user and your staff much more aware that all systems are up and working. Thanks for a good working system.
