Strengths:    Industry Standard.
Relatively accurate.
Calibration is possible.

Weaknesses:    Translation between gauge scale and actual KGF chart.
Requires some finesse to get a repeatable result.
Price as compares to other products on the market.

Bottom Line:   
For years I used this as my only tool for checking tension, and it has done an admirable job and I have built a number of wheel sets as well as true up wheels with it.

There are several shortcoming though. First is that I find it tiresome to alternate between the spoke wrench and the meter constantly. Similarly threading the tool in between the spokes and getting on the narrow part of a double butted spoke is somewhat time consuming.

Second, when comparing with two other identical TM-1 tension meters I found discrepancies of up to 20kgf. Most measurements were within an acceptable range of +- 10kgf but 20kgf could be the difference between a good build and a cracked rim.

Lastly, the repeatability is difficult until you have used the tool for a while. Even with the same tool I would get some smaller (10kgf) variations in tension for the same spoke. This depended on how quickly I let the tool clamp on the spoke, how long it sat there and in some cases the angle that it was on the spoke.

Overall, a good tool but for a serious wheel builder but very expensive compared to the competition like the iPhone based spoke tension meters.
