G'day Andrew, 

Thanks for your question! You sure can use the lids as frying pans. They have foldable handles that can be used to handle the lid while it is over the heat. 

Just be mindful that over extremely high heat the lids may buckle slightly as you'd normally expect. 

I hope this helps! 

G'day Kate,

You can't lock it into a fixed position just generally, but when you carry the pot by the bail handle it does slide up and a small tab holds it in place, preventing it from tipping.  It is essentially a safety feature for when you're moving a full pot about, but it will slip back down as soon as you're not actively lifting.
Hope that make sense!

G'day Chloe,

Yep, there's no reason why these couldn't be used for campfire cooking, but they'd be best kept to hanging from suspension-based open fire cooking, or sitting on a grill plate, instead of going directly into the coals.
Hope that helps.

G'day John,

The hoop handles on the pots cannot be removed unless you are willing to cut the rivets off the hold them into place.  I've used the pot gripper from the Trangia range, which is essentially the same thing, and it works well with this pot set.
Hope that helps!

G'day Todd,

I'm going to say no here. I took my trusty magnet down to the cookware & it's not convincing.  The magnet does stick, but only just and I could literally blow it off if I wanted too.
We had a customer say they worked for him, but they didn't work for our store manager on his. I am aware that not all induction cookers are equal, and given the magnetism on these pots is negligible at best I wouldn't be confident in saying these will consistently work.

Thanks for the feedback Todd, I'm sure it would be helpful for sure!
