Excellent value for price. If you are shopping for an inexpensive auto-ranging bench DMM, this is the one to get. The next step up is the far more expensive Vici VC8145. The display is large, bright and easy to read. Speed and accuracy are both good. DMM reads 2.500V from my 2.5000V reference. Clock is easy to set. Thermometer works and is accurate to 1 count. The main set of test leads are high quality, especially at this price. They are shrouded and have removable tips. The second set of leads are low quality. The accessory screwdrivers are also low quality. The speakers work but there is too much distortion. The manual advises against listening to music when making mV measurements. Aneng should make a less expensive version without the speakers. The AN-888S has limited input protection and no CAT rating. That is fine for bench meter but I wouldn't recommend using it where a CAT II or CAT III rating is required. The power switch is on the rear panel. The fuses are hard to access so be careful with the A and mA sockets!

This is a high quality power bank. It is attractive looking and functional. I gave it 4 out of five stars because the feel could be better. I especially appreciate Xiaomi's realistic ratings. The spec. sheet claims 13000mAh @ 5V 3.6A, which is exactly what the pack delivers. I tested the power bank and measured 12929mAh @ 5V and 2.2A discharge. That is about perfect. 5 stars. The spec sheet lists 20,000mAh / 74Wh at the internal capacity at 3.7V and 13000mAh at 5V 3.6A. Xiaomi specified efficiency is 90% at 5.1V 1A and 83% @ 5.0V 3.6A. I measured 64.4Wh at 2.2A which is 86.5% efficiency if the internal battery is 74kWh. Again this is well within the specifications. Unlike some power banks, this one has Quick Charge 3.0 for both charging and discharging. I checked it with my Anker QC 3.0 charger. It charged at about 9V 2A or about 18W. I recommend this power bank.

I've been using this light for about a month. Good value for the price. The light output is even and is a real help with electronics assembly and repair. Overall fit and qualty are fine. Mine is a bit loose at the base but that doesn't matter much. The maginfier is fairly good. THe image is clear with minor distortion. Much better than most econmy magnifers. It is not as good as a Luxo but this is less 1/10th the price. The lamp draws about 1.126Amps at full brightness. (see photo) The lamp does not work well with a 1A supply.
