I happened to have bought one on Amazon this week. Rating: meh.
Table clamp is okay, but everything else is wobbly. Phone clamp is dubious (but hasn’t dropped my phone). Light ring… it’s so damned small it’s nearly useless. Somehow I expected a standard-sized photography ring, but I’d probably had a drink or two before I skimmed the ad. Giving mine to my kid.
I thought to just give as a kid gift-thx for the adult heads up!
