I have been using my Max handles and they are awesome! Being a home gym user, I have a healthy mix of both standard and olympic plates. The ability to switch back and forth, and even combine them on the same handle makes for a very versatile system. I also recently traveled and can confirm I was able to safely take these through the airport on my carry on and to the hotel I was staying at. The hotel gym had a few random dumbbells up to about 25lbs, and then just a cheap all in one machine with a dusty barbell leaning against the wall in the corner and some random. I was able to load up to about 75lbs on one handle since that that's all the hotel had, but still stay inside a reasonable hypertrophy range and do some rows, single leg exercies and more. With a bit of imagination, I don't think these handles will ever be the limiting factor to your workouts!
