The only place I can see ware happening is just around the edges of the mag safe connection - and that is minor. The plastic fits the laptop snug and does not seem to scratch up the sides - even after more than three years of use. They are very well made and they give you all the parts you need in the box.

With that said let me give you my honest opinion on these. For the price they charge - you get a well made product with lots of extra goodies to make them work their very best. Understand, these are simple, plug replicators, and you will have to do some fiddling around to get them just right. I absolutely love these docking stations. For many people it's a non-issue for photographers, it could be a problem.I have now purchased 4 of these over the past few years. The only real solution if you frequently load content from an SD card -short of undocking every time you need access- is to connect an external USB card reader. Which means it’s inaccessible while the laptop is docked in the Vertical Docking Station. The 13-inch MacBook Air’s SD card slot is on the same side as its Thunderbolt port. The first is that the passthrough port is not compatible with Thunderbolt displays you’ll need a monitor with a Mini DisplayPort connection, or you can use an adapter that converts Mini DisplayPort to DVI or HDMI ( Henge Docks sells these, as does Apple).

And while they won’t affect everyone, they could be an issue for some MBA owners. Unfortunately, there are a few more gotchas because of this design. That exposed MagSafe connector and cable detracts a bit from the overall sleek look of the setup, but it was probably the right choice given that users will always be connected to a monitor, but have the option of ditching the power cable virtually all day if they wish (thanks to the 13-inch MacBook Air’s 12-hour battery life). Need to charge? You'll need to connect the MagSafe power adapter to the top (Credit: Brad Moon)
