I have a Logitech 5.1 system and need a basic mount that would match the style of the speaker while not look too obstrusive . these mount fit the bill . though the mount come with a variety of screw , bolt and fastener , I end up have to buy other which fit my particular speaker . I chalk that up to Logitech , not the mount themselves . once mount on the wall , I like the amount of adjustment that be possible with the mount . it help when you be look to direct the speaker at a particular spot . my speaker be small , say 4 '' wide by 6-7 '' high and 4 '' deep so the plastic mount do not seem to be under a lot of stress . but if you have larger or heavier speaker , I would look elsewhere . I recommend this product to anyone with smaller speaker !!!
