Query: Not well made - but works ok after I repaired it.

I had to send back the first one I received because display was fading in and out. The second one also had a faulty display, but figuring I could be sending these back several times before they got it right, I took a small phillips head-screw driver and fixed the problem by tightening the back myself.But the purchasing of one of these units should not be a do-it-yourself project.The humidity reading is also off by about 3%, but I can live with that by just factoring the difference when doing a reading.Update: I have had this about 5 months now. Since it is holding an accurate reading since I initally fixed it and is working properly, I have upgraded the rating from 1 star to 2, but I still have issues with their quality control.
