Good product. I expected to be larger for 30W laser, but it is very well designed, to protest lens and cool the LD at the same time. It has power control which is very intuitive. Very fast shipping time. Recommendation.

Excellent quality for the price I bought. Easy to install. Notice for everyone: First of all be aware of voltage drop if you use all 5 meters at once. It can be up to 3V and it can be seen with naked eye if you compere intensity of the first and last led segment. This can be avoided if you use shorter led segment and thicker wire. Second due to PWM control of driver next measured current and voltage values are average values. Maximum Current concision for 5 meters led strip per color (when mosfet's are fully opened and there is no pwm control - it acts as DC. Voltage drop on mosfets are around 200mV so on the led strips you have 11.8V) Red: 0.750A Green: 0.700A Blue: 0.580A White: 1.255A PWM frequency is 200Hz. Maximum power consumption for this 5 meters led strip without any modification is around 15W. Overall very nice product, and I recommend it to all.

Excellent product. Very easy to set, and amazingly precise. Screws for mounting the wires on the shunt are M5 and M4, and the holes for mounting the shunt are M6 with 10.5mm apart.

Very cheap drill set. And for that it comes with defects. For example, arithmetic value of diameter of 1mm drill is 0.905mm, for 1.5mm drill is 1.44mm, for 2mm drill is 1.973mm. It is measured with digital caliper. Peaty good if you ask me. Final finish is also good, but some of small drills are not sharpen good enough. Center is shifted and they have wrong angel (see the first picture). Over all it is not for precise and high accuracy work, it is for hobby usage.

I plan to use it for develop PCB. It has perfect wavelength. UV layer (positive 20 or film) is photosensitive in the wavelength range from 360 to 420 nm. Efficiency of standard Hg lamp used for developing in this range is around 5%. This mean if I use 250W bulb I will use only 12W for developing and of course I need to wait 30 minutes to start and must have ventilated room due to generation of high concertation of ozone. With this UV LED strips I hope I will reduce time exposure and remove generation of O3 (because there is no UV-c light responsible for generation of O3). And of course, I will have almost 100% efficiency if I ignore loss thru heating. It has slight wavelength shift toward blue region of around 5-10 nm but it is OK for my purpose. There is high voltage drop between input and voltage on the end of the strip of around 3V. Because of that I plan to use shorter segment. Current consumption one segment of 3 UV led 5050 is 38.09mA so you can calculate total consumption.

Seems to be of good quality, has some weight to the material and upon sun light inspection all cutting ends are sharp. Looks good so far , and I only use for soft material
