I saw these tips on another website reviewing this toilet:

1. Use the lid as a base for the rear legs if you're in snow or soft ground. This keeps the toilet legs from sinking in the ground.

2. For multiple uses (and yes, you can get multiple use of one bag), seal the inner bag (green) in the disposal bag (black) in between uses to maintain a more sanitary situation. Also, to ensure the enzymes can work properly, do not place a paper barrier between uses -- put your paperwork in the white Pett package or ziplock and place in black bag when ready for disposal. In other words, leave the enzymes direct access to what it is they like to act on.

3. Keep the tent closed. You'll have less bugs and flies.

4. It won't hurt your pet if he/she happens to get mixed up on where his food dish is located. These enzymes won't hurt your critter (or your kids).
Once the enzymes do their thing, the mess is considered a non bio-hazard and is dumpster and landfill safe.

I've had a PETT for over six years. My wife and lady friends love it! In fact, it is a primary reason why Nanc is now willing to go out camping with me more than in the past.

I bought the portable tent, carrying case, etc. along with the fold-up toilet. It's a bit bulking and heavy, but well worth carrying.

One recommendation is NOT to purchase more of the toilet bags than you can use in one season. I bought a huge box containing 100 of them. Over the years, the corn starch bags started to deteriorate - not fun to find out in the field. They did last reasonably well for 2-3 seasons.

I have used a few different solar panel systems on extended field expeditions for charging cameras and laptops. This company does a pretty good job for the cost, and has given great service:
