I am using it with cap standard plates and it comfortably allows for 3 plates or 60 lbs. it may be possible to add a smaller 1.25 or 2.5 lbs plate also. Not as quick to change as I hoped. Grip feels good, thicker than twist lock dumbbells so getting used to it.

It works
Very good adjustable dumbbells

I must admit I've come around on the Kensui Adjustabell Max. A few months ago I was rather scathing following the 2-month wait for the product and lack of customer service, but since then I've decided the key is to keep the plates as few as possible, 3 per side at most, and be liberal with lubricants (that's what the kids call a straight line). I've ordered 20-lb standard plates and have fingers crossed that the bolts will fit. Extended bolts are a non-starter as it's hard enough to negotiate 3 plates at a time, let alone more. Besides that, I'd NEVER order anything from Kensui again.

very good product
l am happy with this one

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!
