Bought two of these to put on my Max Transit as they are REALLY HOT! I bought but didn't use hot melt adhesive as Peplink said it would likely void the warranty. I tie them to the body of the device and they cover it perfectly and dissipate heat. The bottom is very smooth so you get good contact. I would recommend them to everyone. The steel body of the Max Transit is painted so I hope there will be no problems with corrosion.
