a few more thoughts from me about the Standard version:
1) it's CHEAPER for the vap and also cost less to replace the whips later on.
2) it's HARDER TO BREAK. the ground glass of the Hands Free is more weak, especially if you tap the whip on a hard surface.
3) the herbs need less stirring because the hot air is directed all around the bowl (you can rotate the whip around)
4) the hot air from the vap is mixed with cool air from air leaks around the loose connection, increasing the turbulence inside the bowl, preventing hot spots on the herb. Also, the vap will stay hot even if a bunch of people hit it in rapid succession. The Hands Free loses heat quicker if used by many people.
5) It's annoying to use a Standard with a water pipe or steamroller because you have to hold the whip at the same time. Or anywhere you wish you had another hand free- such as while you're operating heavy equipment- best to use Hands Free version in those situations.
6) overall i prefer the standard over hands free, but most people prefer hands free.
7) the whip stays cool, not too hot.

A: Choosing between Standard and Hands Free vaporizers is personal preference, as each method has its drawbacks and benefits. The way in which the Whip Handpiece connects to the heater is the main difference between Standard and Hands Free units.
Standard model: The user holds the Whip up to the heater while they inhale, and pulls it away between draws.
• our original glass on glass design.
• easy to rotate around while taking a draw to get an even browning of the herbs.
• glass stays relatively cool.
• can be used (in hands-on fashion) on Hands Free vaporizers too.
Hands Free model: Ground Glass Whip stays connected to the heat source without having to hold it in place.
• preferred by newcomers 2:1
• requires you to stir the herbs to get even browning of herbs.
• tip can become very hot during use - beware.
• whip can be left on the heater for long term.
• grants you an extra hand (what will you do with it?)
• cannot be used in Hands Free mode on a Standard model vaporizer.
Note: All Standard (or Regular) accessories are compatible with the Hands Free vaporizer. (i.e. Standard Whip Handpiece, Regular Fancy Whip, Mini Whip, and Aromabulb.) Hands Free Whips are not intended for use with Standard vaporizers.
