I would rate this product a straight 5.0 but for the following: When I placed my order the offer indicated 4 units of 400mm length available. I bought all 4. When I received the package it had 3 rails 400mm and one rail 350mm. Not what I paid for. I assume some low-paid shipping clerk found only 3 remaining and decided to substitute the 350mm unit as "close enough." I complained to Customer Service but no response. So I got 3 out of 4 rails I paid for. So Banggood gets 3 out of 5 stars rating Value for Price.

Looks good. Nicely cut. Slight burr on cut edge, but after minor filing, passes 3mm filament smoothly. Planned use for experimental reprap hotend.

I have a WLToys Dragfonfly3 drone with a built-in camera gimbal but the little LCD that comes with it doesn't have enough brightness/contrast for use in full daylight. I read a lot of reviews and finally decided on this because it looks like it has the best picture in the price range. It was more than I wanted to spend but I've already forgotten the pain of letting go a few extra of my favorite dollars. I decided to put a floor under video quality because I plan to graduate into full racing drones and a fuzzy picture just won't do in that case. Of course the Dragonfly's VTX is a little weak (don't know the exact power rating) but it was enough to confirm the goggles choice. It also has a head tracker upgrade path, a LiPo battery adapter and a front view camera. Recommended. Well worth the money.

I bought this to replace one of the two I bought earlier to build a desk lamp. One of them burnt out, but at only $5 it's like replacing any other light bulb. These things are so bright I had to move the lamp up on top of a book shelf because the light was hurting my eyes. Two of these over a desk is like strong sunlight. Literally. Mounted on a heat sink with a small fan because they get quite hot. Really quite an excellent value for the $$$.

Just tried this out. Some have complained about the beam size, and at first I thought maybe I got a dud, but it only takes a little fiddling with the focus ring to narrow it down to a needle point. The photos show lines I made freehand with the laser held about 60mm off the surface. No wiring problems, I just plugged in the included power supply and the beam came on. Haven't had a chance yet to try out the TTL input but I'm confident it will work. You just need to remember this is a DIGITAL input (on/off) and you need a PWM signal to control beam intensity. By default this has lots more power than the 500mW 405nM laser my engraver came with. It burned through the cardboard in the photo in a fraction of a second. Had to keep it moving to avoid filling the room with smoke or starting a fire. Recommended without reservation. --Phil M.

I was impresseed how well this item was protected for shipping, considering how little is done for some other items. Even though it was not enclosed in a cardboard box, I doubt a box would have added much protection. That is, the amount of force required to break the glass would have been about the same even if it was in a box, unless the box was made of wood or some other very strong material, which would cost almost as much as the funnel. I suspect Banggood has done substantial statistical analysis of the relative costs of packaging versus return losses. Most packages arrive with just barely enough protection, often none at all for really inexpensive things, so that often items are slightly damaged but not bad enough to warrant complaint or return. That's what I call a well-run business. Anyway the funnel is nice, as expected, excellent value for the price.

The product itself is fine, no complaints at all. I've been using these pins for a while to make connectors and decided to buy a bunch to avoid running out of them. So I saw this deal, 1000 each of male and female, and thought, "perfect!" Placed the order, package arrives after a few weeks as usual, but this time with a little surprise. I thought I'd get a couple of rails a few meters long, one for male and one for female. Instead it was a bunch of little bags with short rails of 100 pins each. 20 of them. AND, they were all male pins. So I complained to Customer Service, and eventually they offered to refund half my purchase price. Fair enough I guess, though I have yet to see the money in my card statement.. So I came back and ordered 2000 female pins, just received those, same packaging, and they were short 100 pins. No big deal since I already had a couple hundred, just a little annoying. Anyway now I have twice as many as I intended. Guess I'll NEVER run out of these if I live to be 100. Great price in any case. I still like Banggood.

It seems that because I bought this thing at the same time as the ROTG02 I have to write a review for this as well before I can submit my words for the ROTG02. Well, I haven't tried this antenna out yet so I have nothing to say about it. But here are some words anyway. You web software guys at Banggood need to fix this silly nonsense.

This is the second unit I bought from Bangood. Call me crazy, but I was having trouble with the first one and figured the second one would work, thus proving the first was defective. Turns out they both work, and my problem was using it with a Samsung Galaxy S3. Even though that phone is in the list of supported phones, it turns out compatibility is a function of the software you have to download via Google Play, not this hardware. When I bought this the popular app was "Go FPV", which requires Android v4.4.3 minimum. My phone has 4.4.2. Darn!!!! missed it by just 0.0.1! So the lesson is this: Before you buy this thing, find out what app you'll need, check the requirements and make sure your phone or whatever you plan to use can work with it.

I received my ROTG02 yesterday and tested it immediately. I installed the GoFPV app on my Samsung S3, turned on my camera transmitter, and plugged in the ROTG02 to the Samsung. It worked right away! I was so happy. For about 30 seconds. Before it finished scanning for the best channel it indicated the USB device had been detached. So I started over, and this time it worked for only about two seconds before detaching the USB. I tried reversing the cable but I had it right the first time. Each time I tried, the attachment interval became shorter, and after only a few minutes it would not attach the receiver at all. I tried a different Android device but got the same result. No USB device attached. I can only conclude that the ROTG02 has failed. I doubt it is the cable because that would not explain the gradual deterioration of function. I csn only hope Banggood will send me a receiver that works. I don't need the antennas and cables, I think those are fine. I need only the receiver.
