Don't know much about your Vapir model except that they've been making it for a long time and it should work OK. The others you mention, SSV and Vapolution, are better vapes IMO. I've got a Vapo and like it a lot-really good combo unit. The SSV is probably the best manual draw whip type vape, and they now have a little brother for it-Da Buddha-which has the same internal parts and is almost $100 cheaper. Hands free is usually just an option-you get a ground glass heater cover and bowl that fit together-it's really just 'one hand free'.
