Pretty Easy. compared to other certain iFixits. Mine did not come with the Rubber base. I guess I’ll have to find some rubber feet for it. The unit gets pretty hot. I Suppose SSD drives will work in these? That would take care of the heat issue.

I bought it mainly because it had a 1TB HDD inside. But it actually works better than a Linksys Router I was using! So I’ll just have to suffer with the fat32 FS on the drive, heh.

I encouraged my brother to buy the Repair Kit and some tools. I did the work for him. I was expecting extreme difficulty, but it was a lot easier than I expected. Using the Guide, I was able to open the device, keep track of the screws, remove the battery and replace it, then in reverse order close up the device, and when I turned it back on, it had a battery with very low wear level (according to Battery Life app by Robert Tkotzyk). I have a 5s with a bad battery and I am awaiting delivery, looking forward to using the guide for that device.

The tool with the two suction cups (I forget what it's called) made opening the device a lot easier than without it.
