I guess it can vary from brand, but it seems a bit odd to be sucking for long periods of time in order to get the vapor. We've recently starting vaporizing and I prefer it rather than smoking from a pipe, I love the occasional joint though.

I'm using a Silver Surfer Vapor, usually takes 3-5 minutes to heat up, I usually have it to the highest setting. There are times when I feel like I haven't gotten any smoke, but I'll blame that on not adding enough green. I feel like I get way more baked in this form, last longer, and I would say yes you use more product but its better for you in the long run. Smoking from pipes was really messing with my girlfriends lungs!! Usually after sucking for at least 45 seconds, I have a big cloud of vapor when released. Maybe your vaporizer is defective?? Does it have a warranty?? :stoned:
