Dionex Spin Flow Mixer for UPLC

Has anyone had a chance to try the Dionex spin flow mixer. They advertise that it accomplished both radial and longitudinal mixing, and does it in a way that is amenable to UPLC.
Also no moving parts.
It seems pretty clever. Has anyone tried it.
Thanks

I compared no mixer, a ASI 150 uL cartridge type, the 150 uL spinflow, and the standard 900 uL shot-filled column on a Agilent 1260 binary pump. The ASI and DX spinflow were equally effective at flows <1 mL min. No mixer was expectedly noisy, and the shotfilled mixer was as good as the other two at that flowrate, but with more dwell volume. I like the ASI because you can buy different volume cartridges and I believe they're more cost effective over the Dionex. JMHO!
