they be pretty good at do what they be suppose to do . relatively easy to mount up and strong enough for pretty heavy speaker -lrb- 2.86 lb -rrb- . of course it be a little pricey but what choice do you have ? these be the cheapest one that get the job do nicely . the only weakness I notice be with the keyhole mount option . it have a little give but then again there be only one screw hold the speaker to the mount . do not be afraid to tighten all those screw down really hard to get they to stay where you want they , the mount can handle it . also , I 'll share what help I to mount they in the exact position I want they in . just a simple guide in case you be have trouble on how to go about it . 1 . I separate the piece -lrb- except for the elbow joint -rrb- . 2 . I mount the end piece to the speaker tightly so there be no give . 3 . I tape up all the wall mount to test out the optimal spot for the speaker then attach they with the supply hardware . 4 . I take one speaker at a time and put the slightly tighten elbow to it and wiggle they around on the wall attachment till I have they in a good position . 5 . I then gently slip off the speaker and tighten the elbow in the right position on the wall -lrb- both the actual elbow and where the elbow connect to the wall mount -rrb- . 6 . ran the wiring to the mount -lrb- good luck , it suck get the wire around live room nicely -rrb- 7 . attach the speaker wire to the speaker and tighten the speaker mount to the elbow . 8 . Voila !!! what a pain , especially on a 7.1 system , but so worth it in the end . wow , I feel like a real handy man now -lrb- or handy person , no offense lady -rrb- .
