Great little sized lab supply. Delivers lots of power and is pretty small in size. Littlebit slow in adjusting voltage down due to output caps. Add a preload to adjust faster. Ideal for small home lab work. Good price for value.

Great microscope. Works well and good for improving vision while soldering tiny components on PCBs. Especially for the older guys under us who lack the seeing quality due to age. The stand is quite stable and is ideal for soldering. The light of the microscope can light up the objects and traces well. It runs quite long time on 1 battery charge. I recommend this microscope for the hobbyists.

Scope received within 5 days in the Netherlands after ordering at Banggood UK. First a calibration is needed to avoid small offset at lowest voltage range. Scope functions well and quite easy to operate. The zoom window (dual screen) works well. 40k memory is for 2 traces (meaning 20k per trace or 40k for 1 trace). There is a small channel unbalance between channel 1 and channel 2. Expect this to be corrected only by hardware as calibration did not solve it. Tested it with my function generator upto 25MHz sine wave. Also tested a class-D PWM output which comes out well (showing high bandwidth).

Product ordered at Banggood in the UK. Arrived within 2 weeks (pretty fast) but the fan was partly damaged (see picture) as the package was shipped by normal mail. Have the 110W version and works well. Used it already to test a lab supply also delivered by Banggood. The electronic load and tester has 2 functional modes. - In Fun 1 the load remains active even when the voltage drops below the programmed voltage (only alarm sound) - Fun 2 the load is switched off when the voltage drops below a programmed voltage. It also shows how much power Wh and Ah is delivered. This is ideal for testing the capacity of your lips cells for your RC hobby The measurement side is actually quite accurate and current / voltage measured is matching well with the measured values of an accurate fluke multimeter. It is a cheap and good solution for an electronic load.
