It's pretty much unanimous on the Blenderized diet board and the Food for Tubie forum that AMT buttons are head and shoulders above the Mic-Key brand. Here is a link to the AMT G-Jet description, it has info for both clinicians and patients so you can send it to your doctors.
AMT G/J button
Actually, it's easier to change a G button than the regular PEG tube since the buttons have to be ordered in half centimeter sizes to fit the stoma exactly. Unlike the tube, a home changer cannot put it in too far or too short, it fits automatically by just laying it on the skin.
For the majority of OCF posters, there would never be a need to change their PEG let alone get a button. My AMT button is now two weeks past the 90 day Medicare allowance and going strong. Even better, for the very first time in 3 years, I do not have that painful granulation tissue that the Mic Key's gave me and that I had to burn off with those silver nitrate sticks.
