Cool stuff in addition to a more powerful desk scope (Rigol 1052). Featurewise is it on the low side, and it is a single channel, but it is totally portable and for once, it has real BUTTONS to set it up. My former DSO quad was more powerful imo, but the user interface was really hellish and the screen eventually blanked out (never understood what the problem was).

Basic, works well. The cable strainer diameter is somehow too big tough. Get ready to buy industrial-gade super thick cables to go with them, or stuff hot glue to fill the voids and keep it waterproof (did not test, but there is a rubber seal) ;)

I used one literally for years, and I was pretty happy to find it on the market. This flux is very fluid, and the tip helps cleaning up thicker flux or to give it a help on difficult soldering jobs without reverting to thick ones. I might buy more in advance, since they do not evaporate when the tip is closed, excellent for the price!

سؤال: Title says its Tip Tinner and cleaner, the pictures show Solder Paste. What is it now??

السؤال بواسطة MaMuCh على 2019-08-14 08:32:21

j.f.34 The containers says "no-clean Sn63-Pb37 solder paste, 24-45µm" indeed. But it certainly does not behave like solder paste though.It is completely dry (like no flux, and the container is not waterproof).It kinds of "boils dry" immediately when you dip the tip in it, and it works well.So I would say there is some sort of beneficial chemical in it.(Nb: I do have different kinds of solder paste)

Nice, comes with a really nice, solid case I did not check that it protects efficiently at this wavelength though.

Works pretty well, burns whatever comes in front even de-focused. Best focus still show a slight diagonal shape, but the burnt dot is small enough that it does not show.

It just took 2.5 MONTHS to arrive...!! No communication at all, even when I opened a claim 15 days ago. But it is there at last, it works and it is fine. Would not buy again just b/c of the abusive delay.

ok works very well, including at night (<10m is quite ok) Note: the cardboard package got seriously crushed in transit but the camera was OK (I bought 2). I guess it helps that these are quite sturdy.

Works well with one MAJOR flaw: not suitable for photography!! It covers the view when shooting movies, but it produces heavy vignetting when shooting pictures (which I do most of the time).

Cheap but mostly useless as it will not hold well on the sticks and most often fall. It also conflicts with the necklace-support extension I bought separately (but this can be fixed by cutting the plastic to leave a notch) Overall probably useless unless you add a leash so it does not get lost almost immediately after being put to use :/

Not sure they would be worth for the arms of a tiny 3D delta printer, e.g.. Suspicious also of how long they would last. Looks like the joint is made by embossing the aluminum casing in a press! I was expecting better, even though I can find uses for them, so globally OK.

I was able to run the 4 of them, and flash them with ESPurna and I use them wit ha local MQTT server (see https://plus.google.com/+JeremieFrancois/posts/LpiZgVKKnvj for more information) Very well done, and looks pretty OK regarding safetly as well (PCB well done, has a fuse within, etc). It even has a warranty label, and it sports only the CE label, no fake FCC-without-an-ID :)

I CANNOT recommend this bulb. I bought two and the first one went dead after less than 1 hour of usage (very slight flickering, mostly off). It was not even installed in an enclosure. This is the E28 12W largest version. The aluminum heat sink seemed pretty good on first sight (nice point), but the electronics inside are crappy if it can die so quickly. I am currently testing a second bulb I received altogether and it ran OK for the last two hours, but only time will tell and I cannot be confident given how ridiculous the lifespan was for the first one. Moreover, I am pretty unimpressed by their low luminosity given that they are stated at 12W. I will better stick with brand names, and pay more (e.g. like the 18€ LightMe 15W bulb which really shines, and which lasted for ~3 years and powered for about 8h a day). Nb: it is probably one of the first time I receive bad stuff from banggood in 100+ various purchases, may be I am unlucky.
