Trevor from Astro backyard did a pretty good review of the 150:

My view of the Strainwave mounts are that they are not necessarily
better performers than traditional mounts, but they look to be (I dont own one btw) much much smaller and easier to manage. They do still have their downsides, such as having to use pretty short guiding exposure times.
If I was looking to go more mobile, I would definitely pick one up, but I get slightly better performance with my Ioptron CEM70 and I never move my gear, so I dont feel the urge.
