I doubt it’d last long mate, a 10mm threaded bar resined into hardcore or even soil dependent on how deep you go just won’t hold what is essentially a big wind sail, also you find the bottom of the post/fixings gives way when using this method
Imo depends what your using it for? If it’s a structure(kennel/shed etc) the stability from the building might just get you away with it. If it’s a fence forget it, hole and concrete is the only way to go, the tarmac won’t give a good hold for bolts
It’s decent and she could twiddle my nob anytime but as with many many modern DJs I would say they’re only actually using the mixer 25% of the time. The rest is just show boating
