Laser/Radar Scanner from Aliexpress ... Fail!!!

A view weeks ago I ordered a laser/radar scanner via aliexpress. After 3 weeks it arrived. So far so good, but it worked for only 1 hour or so.
During this hour it detected one known fixed speed camera, un-detected a seconds one, "found" plenty of other radar/laser sources. I suspect it didn't filter out those parksensors and infra-red motion detection shop door openers.
After stopping to work and successful raising an dispute at aliexpress, I decided to take it appart.

I know a bit of good soldering work, but I didn't find it there. On many places, the SMDs where mounted manually with big zinn drops. Some places (see coloured circles in pics) are oxidised.

One SMD fell out (see pic), that might be the reason for failing.

Lessons learned: Get a decent scanner, spend more than $44.
