I'm pleased with it
Sarracenia seedlings are growing and colouring up nicely under it (which you can actually appreciate compare to blurple), it's heat burden is low, there are no active cooling fans to go wrong, I love the adjustable driver, and most importantly it lights the space evenly.
I have another propagator of a similar size that I have been lighting for a couple of years with a 'Platinum LED' P300. It's a great light, but it is 13000 lux in the center down to about 2000 at the edges, so it doesn't light that space effectively. It would be fine in a smaller space.
Consequently, I just bought another identical MarsHydro and will be replacing it this week
Hope that helps,
Dave
