D: I received 2x 150 Ohm SMD resistors packed with each board - what are they for?

cetoxim For dummy load. Board shuts itself on low mA consumption.

Better than I expected. It uses automatically activates the gyro pointer mouse once the remote is used with its keyboard side down. Otherwise the touch pad is activated.

Poor quality even considering the price - the switch is falling apart, the cable is not fixed properly. Disappointed.

Mine were green - if it matters.. It's okay considering the price, but it will have troubles keeping output voltages stable at fast changing loads.. I tested it with output voltage set to 6.3V and currents changing between 0 and 1.3A (with 1.3A staying 70% of the time) at 9V and 12V inputs. Under these conditions it runs very hot (at both 9V and 12V inputs) and definitely needs a heat sink. But the troubling part is that the output voltage jumped significantly at changing loads - between 5.5V and almost 8V. I would rather recommend the RT8272-based model - also available here at Bangood at a slightly higher price - which is way more stable and seemingly more efficient as it doesn't run that hot under the same condition as above and will not need a heat sink..

This one is decent, I tested it at 6.3V output with currents jumping between 0 and 1.3A (with 1.3A staying 70% of the time) and input voltages 9V and 12V. It keeps the output well stable and the ripple is - mostly - within the promised 30mV, while it may jump up to 75mV at very low currents. Unlike the MP1584-based converters here - which will run very hot at the same conditions as above and will need a heat sink - this one (RT8272-based) runs well warm, but is still far from needing any cooling. I doubt it will hold 2A well at higher output voltages though. Still, it is a very decent step-down converter and its slightly higher price is well justified.

Works perfectly as Quick Charger and behaves the same way as my original HTC charger - it provides dynamic voltages up to 12V (at least with my phone) and currents up to 2A. very happy with the purchase.

a clean build on a good quality PCB. it does exactly what the description says and delivers at least 800mA at the output - I didn't test it for higher currents yet. very happy with this one.
