I tried it for the very first time last night. I used a cheap iron that didn't steam anymore and it got everywhere! I didn't use a tip, so I might have been a little messy. On the other hand.. it worked really well!
When I was in the Army, we used Superglue on our cargo pockets when we pressed our pants. Worked great but lasted several washes. I made a little cash on the side by pressing pants for other soldiers and cutting hair!
