I bought one of those a few years ago. It is not too bad for the
money. There are 3 weaknesses I found.
1. there is an o-ring in the quick coupler that will blow out and get lost
if you forget to discharge the pressure before unhooking the QC.
2. The Nozzle holder adapter is a little rinkydink with the copper seal
that is easy to loose. HOWEVER, a snapon adapter costs more than the whole
set from Tooldesk.
3. I compared readings with the tooldesk gauge vs a snapon gauge. The
Tooldesk gauge had more variability, as might be expected from a less
expensive tool with a smaller dia pressure gauge. I'd recommend at lease
3-4 readings per cyl and then either average or throw out the anomalies.
All in all, it is a good buy for the money. It just helps to be aware of
the shortcomings. It produces results that are a guide, not the
gospel. Before settling on a diagnosis from this tool alone, i'd want to
look at other factors.
