AMR Rev Boxes Any Good?

[project400ex19]

Anybody used a AMR Rev box? I'm going to purchase a rev box this weekand just curious if i should spend the extra money for a good one or just buy a cheap one...If there is even a difference between them. Plz help. I already did a search and nothing came up. Even if you have another brand of rev box and found it has a little bit of improvement let me know thanks again.

i got one for my kids 250ex........works great.

it will now start in every gear........and it doesnt hit the rev limiter like it did.

i think they all do about the same......and the price is good.
