I bought the silver version. Some scratches on the finish. Some of the threaded holes had burrs. Both fimproved with a 400grit flat stone. The lead screw has a backlash of 90 degrees but the screw is still quite stiff. The stiffness was not fixed with a spray of teflon lubricant. Adequate for my purposes, but i'm rating 3 stars because of the high price and because I have seen much higher quality of machine tools coming from China. Possibly other samples will be better. Note: what looks like a handle on the know for quick spinning is actually a lock screw.

I've tested this with a UV spectrometer. It has a strong emission at 254nm meaning it is genuinely a germicidal UVC lamp. (Some cheap LED UV lights advertised on the internet as UVC or germicidal are actually UVA and are not germicidal.) Expensive, but reasonably well built. I'm not sure I trust the instructions which say it will sterilize a surface in 10 seconds. Sterilisation time depends on the intensity of light on the surface you are exposing. That would depend on how far away you hold the lamp.

not a tweezer. It's a very small pin wrench.. Tips do not close closer than 5mm. Closing mechanism is a bit awkward. I havent tested it for it's intended purpose which is to install/remove pins that hold wristwatch bands. Would rate higher but the word "tweezers" in the description.

I tested this scale with a precision 10.000g calibration weight. The scale read 10.01g. Not bad for an inexpensive scale.

Fits me well. Warm. Seems well made. My glasses fog up with the mouth-flap in the intended position. But I put the mouth-flap upside down so my nose is not covered. Then my glasses do not fog up -- provided I don't breath through my mouth. I can put the hat on and take it off without having to remove or re-attach the mouth-flap. On the inside of the hat, at the very top, is a bare metal rivet that goes through the hat to the outside. I thought this would be a cold point. But I can't feel it. I guess I have a flat head. Some users might want to cover the rivet on the inside.

adequate money clip. a bit expensive for what you get. But no sharp/unfinished edges. Not much else can be said. Doesn't take batteries, inst IOS compatible, firmware not downloadable, not usb-c compatible. :) Does hold folded paper money.

warning: no protection against polarity reversal. I destroyed mine that way before I could fully test it.

I've used it only at about 3 amps. But it works well controlling a small DC motor. Stays cool. Motor speed is reasonably constant once set.

Works well. I replaced the euro plug with a US style plug. It works fine at 115V. Note however the wires for the ac input are very thing. It takes some care to connect them to a replacement 115V plug. Measured voltage output is from 8.9V to 24.3V. I'd by more of them, but I just notice the price has gone up from us$8.00 to us$13.00,

Q: This is NOT an Electron microscope.

Asked by henrivdr on 2019-04-08 08:53:31

danko No it's not. It uses light to form an image, not electrons. It's better described as an "electronic microscope". It's a digital/video camera with a lens.

25 days to deliver to Canada. A beautiful piece of glass. (Ok. I have a thing for lab-glass). Delicate glass but was very well packaged and arrived perfect. I feel confident to order more delicate-looking lab glass from banggood. Missing the tiny ring that retains the glass stopcock. But stopcock fits very well.

Quality screwdriver. Well thought out. Best item i've bought from banggood so far. Includes a large number of screwdriver bits. Most useful to me are the tiny philips bits PH0000 though PH2. The tubes use to store the bits provide quite compact storage. But I would recommend opening them over a table, or open box, as i've had a few fall out. The manufacturer has included a case which holds the screwdriver and one of the three tubes of bits. Regrettably there is not quite enough room to close the case when a bit is still in the screwdriver. They've also included a base to hold the screwdriver vertical on your bench, suction cup, magnetizer/demagetizer, a magnetic mat to keep your tiny screws from rolling off your bench, and a little jar of common tiny screws. A very complete set of accessories. Also the box and packaging is very very nice. Would make an impressive gift.
