This is a good product, encapsulated with light detection, so it only activates IR LEDs when dark. I'm happy with it. Because it wasn't identified on the specifications, user's need to know: The initial current draw is 400 mA at 12.00V, per illuminator. After the emitters warm up, the current drops to about 385 mA. At that point, the Illuminator is comfortably warm to the touch. Then, raising the supply voltage to 12.65 Vdc then the current remained at 385 mA. , which is no surprise LEDs are current dependent devices as the voltage may vary within +/-5%. A 12Vdc, 500 mA power source per unit is sufficient.

This Horn is advertised at 130dB, which would be painfully loud when testing up close. It was not painful. I would estimate the sound to be loud at 115dB, which is sufficient for my needs. The entire body is plastic with 2 blade contacts for + and -. Only the support bracket is metal. I will use my own mounting screw and solderless blade connectors with wire. Shipment was very fast.

This buck converter adjusts the current and the voltage. I did not test it to the 300W limit, which is only available at the higher voltages. My application requires high reliability in extreme heat. I need it to provide13.9Vdc at about 1.5A from a 17.8Vdc source and at this voltage, the output power of this converter is limited to about 18 W, which is close enough for the very hot environment where I will use it. I purchased 2 units. One of them had the 2 heatsinks leaning toward each other and the other one had the 2 heatsinks leaning away from each other. Since they were both different, I attribute it to manufacturing inattention. Both units work fine.

I've purchased similar units over the past 2 years. This unit arrived and to my surprise, it has provisions to use either AAA batteries or a 3.7V Lipo battery which was included. So I consider this model to be superior to my previous units purchased elsewhere for about the same price, because one of my older units only had provision for use of AAA batteries and no backlighting capability and the other slightly newer unit had backlight capability but only a provision for the included 3.7V lipo battery. So I'm happiest with this unit.

Good value for the cost. All supplied parts are sufficient for attachment to faucet and the wall/mirror. Mirror mount is through a stick-on tape, which isn't going to be satisfactory if the wall is painted or has an uneven texture. The sprayer hanger can be removed from the mirror sticker by 2 nuts, leaving the aluminum hanger available to be attached to a wall through two holes in the sprayer hanger. Rubber gaskets/washers are of good quality and enough are supplied for any installation. The sprayer has a selection of spray or non-spray. I wish it had a position for off at the sprayer in addition to the faucet, and although not necessary, it would be a good convenience. No special tools were needed to attach this to the faucet and a mirror. Some tools and 2 screws may be needed to attach it to a wall. I'm very happy with this unit. I recommend it.

Very nice display, very capable for many component types, built in calibration function, professional looking. Good functions like auto-power off, but I wish it would have a longer delay than it is currently able. It takes 10 sec. to display opening screen and do a battery voltage check, then start measurement (this takes another 5 sec.). The result is displayed for 5 sec and then it automatically shuts off. The max on time is 25 sec if one opens the case and modifies the board for the appropriate 2 digit logic states.. The problem arises when several components (capacitors - check value and loss) need to be tested, and each parameter checked to see if the component is good. The unit shuts off too quick to be able to remove the tested component and replace it with another component fast enough to press the retest button. So, the next component needs restarting the test, which wastes time and battery power. So, it doesn't take too long to deplete the charge on the battery. My first upgrade for this unit is to install a reasonably sized battery. Also, there is no visual indication when charge is complete, so you need to turn the device on, possibly several times, before the display shows the battery is fully charged. Without these improvements, I give the quality 4 stars while the other areas are 5 stars.

Overall, quality seems reasonable. All parts identified in the picture were included. Packaged with sufficient protection against damage. The cylindrical holder for the sprayer was unfortunately plastic, but the hook is metal. Sprayer, valve and fittings are metal. The hose is surprisingly flexible! The hose covering is decorative plastic not metal. Value for the price is high considering place of manufacture and some plastic components.

Copper appearance is bright for most of the boards. The top board with the copper exposed did have slight discoloration, but board resurfacing will be needed for final use anyway. I'm happy with this purchase and my next purchase will be for double-sided copper boards.

Assortment is as expected. Each row of resistors on each page is labeled by resistive value and 1% tolerance. I'm happy with the order. Unfortunately, it took a long long time from ordering to delivery, but I'm happy it finally arrived.

The gloves fit reasonably well with compliance when making a hand fist. The knuckle protection is reasonable in value, but I wonder how well it will perform in a crash. All of my riding is on road, mostly below 45 MPH. The knuckle protection appears to be molded directly onto the underlying material. So I believe it will work good enough for most of my riding, and probably as good as thin leather gloves, but with better ventilation. I would no use these gloves for cold weather riding because the material breathes too much but should work well in hot weather.

I'm a second time buyer. I purchased 3 more! Small and discreet, best for keychain or anywhere you want to leave it plugged in without having something protruding from a laptop... These are good quality and they stood the test of time (2 years of use) -- highly reliable.

I bought 3 of these. I tried 1 so far and it works good. It protrudes very little when plugged in, which is a good feature. The other good feature is the light at the end, so it catches your eye if you want to remove it before leaving your computer/device. I highly recommend this.
