I am looking at buying one of these any feed back positive or negative?
It is on the low end price-wise, but is a middle of the road system. You get more than you pay for.
I am operating a Dynamis on one of my layouts.
It is a very good value, but does have it's limitations. The major one being,
without a VERY expensive additional box, it will not read decoder CV's.
This does effectively limit the ability to program decoders.
Being an IR based controller, means you must be within a limited angle to
the receiver, a limited distance and have a clear "line of sight". IE, scenery,
buildings, and locomotives or rolling stock, etc can't block the "line of sight"
between the hand unit and the receiver.
There is also an annoying glitch. The turnout direction indicators are
backwards.
When the unit indicates the turnout is "straight through" it is actually set
to the turnout and vise verse, when it indicates the turnout is set to
turn out to the siding, it is actually straight through.
Personally, I have found that, if you have a large number of locomotives
entered, as I do, it becomes somewhat time consuming to scroll through a
large number of entries to change which locomotive is under control.
But as I said, it is a good value. Most other wireless controllers are
RF(radio) and accordingly far more expensive.
