First impressions of the glow fob from TEC start with the packaging. The plastic case that the fob arrives in is an immensely well thought out and well presented case. Included is the fob itself, a small gate clip and split ring. The fob itself (in this case, the aluminium version) is about 4cm long, and around 5mm wide. The machining on the fob shows little to no markings besides some vertical lines that add nicely to the colouration (in my case, the charcoal).
