I bought this to wall mount a 27" iMac and a 27" display (the iMac's stand is too short and, in any case, the two screens are at different heights). I chose this after looking at a lot of Vesa arms. The arm is well-made, easy to adjust and comes with all the fittings you need - including wall screws and shield anchors. The standard monitor plate was all I needed to fit mount the iMac, but the arm comes with extra adaptor plates and a comprehensive range of M4, M5, and M6 bolts to secure almost any screen you could imagine. The instruction leaflet is clear, comprehensive and in proper English.

The iMac and screen are now securely mounted at equal height and I have a clear desk to work from.

If you're looking for a Vesa arm with this sort of reach, for a screen up to the specified weight, you'll find tis one, especially at this price, well worth the money. (Posted on 1/20/12)
