I am very satisfied with this device in general. By cons I am very disappointed because all the items were not in the box. This means that I do not have the housing cap (if I want to leave the case without lens) and I have not the rear lens cap. This seems a small thing but these devices are very sensitive to dust so no plug can be damaging and for the purpose it is important to protect the thread for attaching it to the housing. So if you want to buy one ask the question, it will save you from buying more. After an exchange I got the complete kit. I am very happy with this arrangement and this unit.
