Total Failure Of Doorbell 2 Unit

Gentlemen,I got doorbell 2 & I faced couple of issues. First off all, I've installed the doorbell by myself & I've attached it to the solar panel. It worked initially for only 2 days then it failed totally. In addition to that, the dealer in my place change the device for me for free & the new device was working fine except not charging from the solar panel. I'm living in a place where the temperature between 120 to 130 F during summer (Saudi Arabia). Now again the new device failed as the previous one due to unknown reason. With all respect to the features of this device I'm totally disappointed with the quality of such kind of product I'm not going to recommend it to anyone.Looking forward to hear from you.
