Input:
As a city dweller with a small apartment and a glass-top stove with limited headspace, I settled for the 910 model capable of processing four quart jars in one go. Love the workmanship of the unit, and the metal-to-metal seal. It just looks and feels sturdy. After lubing the contact parts with vaseline, I learned the optimal temperature range for 2-3 steam vents per minute and proceeded to can a range of vegetables, meats, and low-acidity fruit  24 jars over a couple of weeks. I used only Ball quart jars (http://amzn.to/1GwYieN) which all vacuum sealed fine though I did experience some loss of liquid in the initial batches, something I attribute to removing jars too quickly.

Can particularly recommend the Simply Canning website (http://bit.ly/1qtmDI1) which has excellent instructions to get you started. Also picked up the Ball Complete Book of Home Preserving (http://amzn.to/1ntatwv) which is superb for recipes down the line, and the Presto 09995 7 Function Canning Kit (http://amzn.to/1smtrIb) to make life significantly easier.

Have suffered no problem using it on my glass-top stove, but that was one of the reasons I got the smallest model.

A solid five stars
