The way I see it is: This is MGL's structure. CEO - Rainier, Designer - Rainier, Software Developer - Rainier, Support - Rainier, Documents - Rainier, Factory - South Africa. You have one source and one man for everything MGL. Now, I'm not knocking Rainier's abilities, he's a smart guy and thinks outside the box. Rainier's problem is he takes no interest in dealing with customers and problems, nor will he add any smart people to join MGL to advance development and support. Sure Rainier pops onto the forum every so often to see what's not working, that he won't address, or view suggestions from pilots that he'll never implement. And Rainier can do as he pleases, but MGL had a very long reputation for poor support, bugs and poor documents long before I got involved, and I knew this going in. So I guess it's on me, as well. Matt, USA MGL, is as good guy and very helpful, to a point, but can only swap parts. Matt does not design hardware or software. MGL's EFIS's have far more configurable inputs, outputs and screen options than the competition but it's attraction ends there. When I was looking into installing the iEFIS I asked a friend of mine, who's business is installing avionics, what he thought of MGL EFIS's. He said it best; "MGL is like building your own computer system, you put in all the components, install the software and you get what you get". And that's just what I got. OAT 20 degrees too high, EGT's 200 degrees too low, fuel flow never worked (3 Red Cubes, 2 RDACs), compass turns sideways every so often (2 compass's), other temps questionable, Data viewer is a joke, poor documents for the screen designer (just got to figure it out on your own), auto pilot never worked well, etc. And all I've ever gotten from Rainier is "Crickets". Fool me once.....
I'm not saying that the other EFIS companies don't have their bugs and problems but the main difference between them and MGL is they have support "people", not a non support "person". The others take the input and make their products better and add more features. MGL.. Not so much.
