    It's a neat little kit. Everything is nicely labelled so there's no way of making error. Reason why I removed one star for Quality: ceramic capacitor labelled "104" was missing I got 2x 2.2K resistors instead of 1x 2.2K and 1x 2K resistor. The legs of the potentiometer that was included in the kit didn't fit very well in its dedicated holes on the PCB. Reason why I removed one Appearance star: The effect is not very visually pleasing. The effects hurts my eyes even on the slowest strobe setting. But I guess that's what the strobe effect is for, right... I'd happily buy this product again for sure. With so many soldering points it's great for practicing soldering!

    Easy to build, although care must be taken to connect the power supply to the LED PCBs. Through a trimmer it is possible to adjust the speed of the effect.

    Good, very good. Easy to build. Pay attention only to the polarity of the LEDs and to quickly solder the integrated circuits (they are without socket). Beautiful stroboscopic effect. Nice.

    I love these little kits because of the challenge that they usually present. First of all I get an hour or so of relaxation building them. There are sometimes some challenges along the way. This kit for example had a few poorly drilled holes on the board which required redrilling. There are no instructions other than the screen printing on the board. My kit came with the screen print specifying a 2K resistor and the one supplied was a 2.2K. this is not a big deal but it might confuse a first time builder. After the kit was built I hooked it up to the specified 12 Volts. It ran for about 10 seconds before the CD4017 heated up and shorted out leaving all three banks turned on. I inspected the build for errors and I could find none. The CD4017 was removed and the individual driver transistors and related circuitry was tested and found to be in good working order. The data sheets were checked to verify that the CD4017 could handle the current it was being required to source and this too was well within tolerances. While the CD4017 that was supplied with the kit had a Texas Instrument symbol on the chip I suspect that it was probably a forgery. I put in a genuine TI CD4017 and the unit took off and functioned perfectly. I had fun building and trouble shooting. If your unit's CD4017 heats up or if all the banks come on at one time just get a real CD4017 and replace the one that comes with the kit. The first picture shows the counterfeit CD4017 on the right and the real one in the unit. The second picture shows the unit in operation. John

    Good small kit to learn assembly. White LEDs are bright. The red LEDs are ok and the green LEDs are kinda dim yellow. Should be all white for maximum strobe effect. Some cable sockets may not fit. Component list is written on the PCB.

    a great project for any beginner, but the only thing was a missing part (Ceramic Capacitor) which i have ordered separately apart from that its still a bargain for the price and it was fun to build but will have to wait for photos until the capacitors arrive

    Nice kit to practice soldering. I had to replace 2 defective leds to get it perfect. The pcb's have a good silk screen so the assembly is easy and clear.

    I built and all was well. But mine light 2 right, 2 middle and 1 left and then repeat.
