My .02 and about all it is worth.... I have a more expensive Vlair 400P. It works great. But knowing what I do now.... and if doing it over... I would save the cash and get the MV50. I would also recommend the same to others. It has a pretty good track record and I have seen it used by others on the same trail run and could not justify the cost difference.
Now, I know it is a little more expensive than the one you linked. But it is a damn good unit for not a lot of cash. So might take a look at it. There is also a thread here someone (cant remember who) installed it under the hood in front of the air box.
Good luck and if you do get and it works out... let us know.
