Digital Torque Wrench Question

[TxDoc]

I was considering this GearWrench digital (electronic) torque wrench:

Features and Benefits

Three torque wrenches in one (25-250 ft lbs, 300-3000 in lbs, 33.9-339 Nm) provides superior versatility
No need for mechanical recalibration which provides savings to the user
Measures the maximum torque required to REMOVE an already installed fastener “Breakaway Torque.”
Ideal when service manuals are not available or when working on 3rd party installed aftermarket parts. The torque required to break free a fastener can then be applied as the torque value when reinstalling.
Excellent for restoration work or service on custom built vehicles.

The GearWrench Electronic Torque Wrench 1/2 in. drive has the ability to replace three torque wrenches. 25-250 ft lbs, 300-3000 in lbs, 33.9-339 Nm. No mechanical recalibration needed, which means savings to the user. 4 simple buttons- Power On/Off, Torque Target Up & Down, and Convert Units (ft/lbs, in/lbs, and Nm). Buzzer with Red, Yellow, and Green lights to alert when target torque is being reached. LCD screen with backlight for easy reading of torque values enclosed in a shock resistant housing.

Two questions:

1-Does anyone have any experience with this?

2-When they say, "Measures the maximum torque required to REMOVE an already installed fastener “Breakaway Torque."....I never considered this before and have no idea...IF it does measure (accurately) the torque required to remove a fastener, then does that equal the torque the fastener was originally required to be torqued to, or not? Just wondering.

Thanks for any help
