Pro tip: don't buy those cheap wireless door sensors on Amazon

I grabbed a 10-pack of no-name wireless sensors for $35 last month thinking I was saving big. Installed them at a client's house in Denver and three of them stopped working within two weeks. The client called me back complaining and I had to eat $120 in labor to swap them all out for Honeywells. Anyone else get burned by cheap sensors like this?

Nah, sometimes cheap sensors work fine in milder climates like mine and you just got unlucky.

Installed a 12-pack of those for a buddy's rental property in Phoenix last year. By August every single one had failed, the heat just cooked the batteries and the circuits. It's the same pattern with cheap Amazon stuff across the board, not just sensors. People think they're saving money but they end up paying twice, once for the product and once for the labor to fix it.

Read this thing from a security guy online who tested those cheap sensors with a multimeter. Said the internal voltage regulators barely hold steady past 80 degrees. My own experience backs that up. Had a whole batch fail at a client's place in the summer humidity. Labor costs just kill any savings. It's not even close.
