I needed a mixer for small streaming/video gigs, including outdoor events with no AC power, plus a backup for my main PA mixer and a replacement for my Zoom L6 for small recording tasks.
It does everything I want but not as well as using more expensive specialist tools. Probably the best thing is the battery power, so it's very quick and easy to get out and set up at home or take to an outdoor event (I have some battery powered PA speakers). As a multitrack recorder it's pretty good and a very useful balance of functionality and portability, it's very compact for an 8-channel mixer. I've added an ART dual pre to make it a true 8 input microphone mixer.
But I would always use my Soundcraft ui24 digital mixer in preference if circumstances allow. The L-8 lacks any parametric EQ or compression, and no EQ on the outputs, the hybrid digital/analog controls are fiddly and require concentration, so it's not intuitive.
So not perfect but a wide range of useful functions, especially if you have good quality inputs that don't need much treatment
