They do a great job keeping the wife's knives sharp! To make life easier for me, I made a simple jig that keeps the sharpening angle to around 20 deg. The only problem with the sharpeners i noticed was that the 2000 grit was slightly concave otherwise I'm pretty happy with the purchase especially since I got them at 65% off during a promo.

Highly recommended ! I liked it so much that I have now bought two. I am able to focus the laser to well below 1mm - see photos. My only complaint is that a cover should be provided for the exposed electronics but overall a great purchase and delivery was under 2 weeks. Thanks to Banggood. !!

Great price. I'm using these as a reminder that my garage doors are open. Note that the black square part is plastic so it may not be suitable for the constant pounding of an assembly line but for my couple clicks a day its good value.

This is a very interesting device; I bought it to monitor dust levels in my home workshop and to measure if dust filters were being effective. With it i was able to significantly reduce dust to the point that my Indoor air quality now closely follows with local Outdoor air quality monitoring stations !! I added a wireless connection so it could be moved around and still log data to my shop PC. The only problem I encountered was that the supplied connector would not stay connected no matter how hard i tried to press it in. Eventually i hot glued the connector in place. Even with the connector problem i would still highly recommend this item.

Very Impressive ! Professionally vacuum packaged and a 2 week delivery to Canada. I really like the solid aluminum mounting bracket which made it easy to modify and mount to my home made CNC. Unlike other modules this laser is off until you press the test button. With careful focusing (I usually focus on a black razor blade using a head band magnifier from Banggood, laser goggles and PWM set at 1% power) the dot approached 0.1mm. Its very difficult to get a picture of the focused dot but i tried below. For my needs (wood engraving) it seems perfect and cuts through paper like butter at 30% power. I have not tried deep cutting wood yet but so far i'm very impressed with the quality of this laser compared to others i've purchased. I'll update in comments if i run into any problems with it over time. Thanks to Banggood for providing a great product at a great price !

JonDun Anincredibly useful review

BigMac 04/03/2021
These aluminium alloy rods, have a flux core, and will brass aluminium, copper, and steel (dissimilar metals) to self or each other. They are mostly useful for crack repairs in aluminium castings, to prevent the crack progressing (drill a tiny hole first just beyond end of crack),*and to stop gas or fluid leakage. Offer price was a no- brainer purchase. Already I used a rod to seal a crack from weeping oil. Must have surfaces scrupulously cleaned using denatured alcohol, brand cleaner, cellulose thinners or similar. Clean crack and surrounding area thoroughly. Be careful because rods melt at very close to the base alloy of casting in some cases. Don't be too fierce with gas torch. Butane is enough heat, but you can use propane mix,for MAPP gas. Acetylene is NOT required. Remember you are BRAZING, and not Welding !

VERY comfortable and VERY effective. Unfortunately the rubber part fell off after 3 weeks of use however i have ordered 2 more with hope that they will last longer. If the manufacture could ensure the rubber part stays on better, or advise on how it can be re-attached, it would easily get 5 out of 5 stars.

JonDun@olmez67 Youcan supply PWM to vary power level using a TTL signal. It also supports PWM in the voltage range of DC3.3V-12V (See the specification table in the description)

Given that this is a fairly expensive piece of equipment some documentation and a cover to protect the exposed electronics should have been included. Now the good news: With careful focusing (I use a headband magnifier from Banggood, laser goggles and power at 1%) I can get cuts about 0.2mm wide in wood !! When unfocused the beam becomes rectangular. This is my first laser and I bought it to do wood engraving on my 2mx3m homemade cnc. It seems perfect for this application. I have not tried cutting but it slices through paper at 30% power like butter. Note that the laser is at full power when first plugged in so PWM is important to have. It was delivered in under 2 weeks to Canada and I'm very happy with purchase - Thanks Banggood ! :-)

JonDun@popadrian23 I used a small piece of aluminum channel to hold the laser module and a piece of flat aluminum bolted to the channel to hold the electronics. The flat aluminum piece can be seen in the last picture between the module and electronics. I've been using the laser for a year now and remain VERY impressed with it. Good luck :-)

I bought 2. Good image quality, nice metal enclosure and I can confirm they work below -20C. But, config software is very poor. For example, simply changing frame rates would crash the IE config software and lock me out from connecting again. No support for SD Card recording or remote pan, tilt, zoom even though the supplied software has these parameters. I ended up using wired LAN because I did not want the cameras impacting other WIFI devices. It took a lot of hours getting these cameras setup how I wanted. Overall they have been working well outdoors in cold conditions since Nov 2017 so I`m happy with the purchase.

OK but there were sharp edges from the lens on the nose piece. It was fairly easy to filed this down so that they could be comfortable to wear for long periods.

JonDun The description says Input voltage (eg Vcc) is DC12V. and Vout is 5V.Maybe that helps?

Today i planned to start working with the HFS-DC06 Module. Unfortunately it does not work at all after applying the Vcc of 5 VDC. How can it happen to ship untested electronics? Please send me an replacement module as soon as possible.

These leads seemed to work ok until the small end cap came off and stuck INSIDE the connector of my DVM . This prevented the DVM from working since NO leads would now make contact. If the end cap had just fallen off in my hands I would have given 3/5 stars but this defect completely disabled my DVM from working when i needed it so it gets 1/5 stars. BTW, I'll be pulling off the other end cap before it comes off and jams up another connector.
