The only 'negative' I see is it's 5 gallons. If you're not brewing smaller than 5 gallons, then you would definitely need to use a blow off tube. Some here argue they are more oxygen permeable than the BB carboys.
I have one of those I'm going to use as a secondary for some fruit beer or for batches too big for my 2 gallon buckets and too small for my 6.5 gallon buckets. I figure I can just use them so many times, then just recycle them for a new one when I go to buy more water for brewing. If I do a beer that needs some aging, I'll just use one of my cornie kegs.
