Buying a cloned device for a small fraction of the original’s price is often not a good idea, unless you’re handy and like to tinker. One example are cheap Vitamix blender clones, made out of the cheapest parts the manufacturers can find. This guide shows you how to replace the ball bearings in a blade assembly of such a clone (probably works for a real Vitamix too), if your jar is leaking brown oil or the blades became stiff. This saves you from buying a complete blade assembly unit and upgrades the drive train to better durability and smoother operation.

About one week after the 1-year warranty of my Nexus 5 expired, its power button began to fail out of the blue, showing the following symptoms:

• The phone would often show the power menu, or lock itself and turn the screen of
• It often shut itself down, and got stuck in a bootloop, making it even impossible to access recovery

This seems like a frequent problem and results from a defect power button signaling its pressed state, without being pressed or stuck. Hard tapping on the phone around the power button can temporarily help to get it back to its normal “unpressed” state, which makes it usable again and interrupts bootloops. Still, this gets more and more annoying over time.
