Yep its all a good idear and great when ya get one that works, but unfortunatly i wouldnt trust any of the components in a car, motorcycle, helicopter, plane ect, so all in, a bit racked off, seeing that its my lungs at test, they need to bring the price down and in line with its worth.. to say theres a lot of clones of mods about may even be an understatement, ive been heavy handed tearing some apart to build outher things and theyve been solid and reliable, but you can get the impression at the moment that we are all nurse mading these boards allong for the research of the firm and payed with cash and hours and hours of headach and building time..to find that after a matter of hours use a chip burns out or screen ribbon cracks, surly logical explanation is cheep components. And poor design. to suggest that all mod builders including factories on a comercial scale who have encounterd problems is down to theirselves... dont think so... built six sent two back currently still waiting for the second to show up, ive done the work allready now got to redo it, saying sorry for your inconvinience aint hood enough realy when your compedent at soldering and assembly, am looking at the SXJ boards... I do realise fairness to the company they could put foreward " this is how many weve sold in the last ten months and this is how many weve had back scenario" which makes me feel there are several posts on the forum where private builders have sent several back, myself included, 2 out of six, but not buiying direct makes me question have the boards been buggered about with by the merchants I bought them off, myself 2 boards each off three diferent merchants, evolv should seal the box with tamperproof tape to cover the back of themselves and the merchant, but also the question of b grade and a grade..........
