There are multiple threads on the qualities (and faults) with screens from various manufacturers. Like tyres, gloves and Marmite they each have their fans and their detractors.
Any screen will always be a compromise not least over what YOU (at six foot six, with an open flip-front helmet at 70 mph) will want over what the five foot four fellow with his full face Arai will value.
You'll also see from a very recent thread that it doesn't make much to make a fellow's opinion change at very short notice. The chap was dead happy with screen XYZ, singing its praises..... Until that is, it rained! It is now verging on the invention of the devil and will be going up for sale, along with his (new) helmet. Life, it seems, is never a real bed of roses.
My suggestion.... Google up MRA Vario screen and read all the reviews and / or do a search in UKGSer. Just because the review is not personal and might be from a magazine / another website, it matters not one jot. Then go and look at one in the flesh. If you like what you see (several bods buy on style as much as anyting else) buy it. If it's 'great, mate' then indeed, great, mate. If it's dire or does not do what you imagine, sell it very quickly through UKGSer or on EBay.
One tip.... Just before you put it up for sale, don't post a private review that the thing is total crap; who knows another bod may just be out there looking for one
