Review on AVLT Power Aluminum Spring Monitor Extended by Jason Mulah

I've bought several different swivel monitor arms in the past and this is the only disappointment. I have relatively light monitors on these mounts and can't be made to stay in any vertical position other than fully down or fully raised (a little unreliable in the up position). The other Ergotron and Revain Basic manipulators stay in whatever position I put them in. The arms are arranged in rows, so the two monitors on those arms are the only ones I can't perfectly align with the others where I need them.
