Any idea how far (range) this sensor works?

One type detect the (relatively high) frequency of the sound of breaking glass, those vibrations don’t usually transmit through a structure as well as lower frequencies. So with that in mind, they work really well, particularly in line-of-sight, and even in adjacent room installations.
This type, which detects a broad range of vibrations, is typically not used in professional alarm installations because transient noise from outside can affect the sensor. For example, if you live in a duplex and have Tim Alexander living next to you, you may get the occaisional false trigger.
Cool, thanks a lot for that!
I would consider this a shock sensor. I have 10 of them and I don’t see how it detects glass break as @Bulldoglowell mentioned.
Glass break detectors are different from shock detectors. They work by analyzing the acoustic signal to match the signature of glass breaking.
This Vera sensor says it is Shock & Glass:

But I’m trying to say is that this is more of a shock sensor only IME…even though it says glass in the description.
It might detect broken glass if it falls off the broken window producing a shock 
Does this shock sensor work in the US with Vera? Anyone have one that can report on its effectiveness??
Yes, I ordered it and it shipped to San Diego. Don’t know why it’s stuck in the International - Canada category.
I ordered one from the Vera website and added it to my Vera3 on 27 January. UI 5, Firmware version 1.5.622 .
The box it came with was labeled “ZS 5101US Shock Sensor” and “Made in Taiwan.”
The Installation & Operation Manual refers to the ZS 5101US as a Wireless Shock Sensor. The introduction in the manual states "This sensor detects the vibrations made by an intruder trying to break a window or door. Additionally, the Operation section of the manual begins with “Vibrate the ZS 5101.”
When I ordered the ZS 51010US, I assumed it would be an acoustic sensor triggered by sound waves, since it was advertised as a “Shock, Vibration & Glass Break Sensor”. Apparently not. Inside the sensor, there is a spring with mass that vibrates when the sensor or the surface the sensor is mounted to is tapped. The sensor includes provision for increasing and decreasing sensitivity using a potentiometer inside the sensor.
I attempted to trigger it using a Honeywell Glassbreak Simulator (Model FG-701) without success. It appears to respond only to vibration. My experience, thus far, is that the ZS 5101US is a Vibration Sensor that may detect vibrations made by an intruder trying to break a window or door on which the sensor is attached.
Sorry to have to clarify, but mentioned how it is not like a conventional glass break sensor, rather it is affected by a broad range of vibrations. I thought I was clear in explaining that this unit was different, if not I apologize.
Breaking glass does create a violent shaking movement caused by an impact, explosion, or tremor, which is also known as shock. I am sure that the manufacturer’s claim as “Glass Break Detector” is probably justified and easily verified.
The big differentiation is the range of frequency (as Richard further clarified) and as I mentioned, transient vibrations which you may not wish to affect your sensor. For example, you may not want to have your sensor signal because your neighbor started his Harley, or your upstairs neighbor enrolled in tap dance classes.
My actual experience with this device is OK. However, my house is a single story concrete slab, breeze block construction with hurricane glass on the entire envelope. People refer to our house as ‘the tomb’ in reference to how quiet it is when they go to bed.

I was agreeing with you I added a comma.
