The unit is very compact ( gain of room for all the functions offered ) and the value for money is great. However keep in mind that this has a lot of electro-pneumatical devices installed in one box. The failure of one component is likely to render the box useless if you use all the functions. So in theory, and despite the fact that each component has a good reliability rate taken separately, you divide the reliability by 5.

That said I have two planes installed with EV5U and EV5U pro and have had only two issues ( no failures yet ):
1) is the slow learning curve in programming the unit ( the ''chinglish'' manual does not help)
2) is the high level of EMI outputted by these units that have required relocation of the receiver in the two planes

On my recent builds I have gone back to separate elements because I like to keep it simple and for ease of replacement in case of a single component failure. Also I find the ergonomics much easier to implement with separate elements: you cannot bury the EV5U pro at the bottom of your plane since you need to be able to read the display out.
