I'm updating my review with more information after 1 year of use:

I was needing a wireless light that I could use under the hood of my car, but I did not want to spend a lot of money on anything that I was not going to be using often. These had some good reviews, so I thought I would give them a try. Here is what I think of these lights:

Pros:
- Price: I think the $15 for 2 of these lights is pretty good. They are not high quality or something that would replace heavy duty lighting, but the price of these make them a good addition to a glove box or backup light when you need it.
- Size: Some people may find this as a negative, but I like how small these are. I am able to store them in a glove box pretty easily, or I can put them on a shelf in my garage and not feel as though I'm taking up a ton of space. The actual light bar is a great size for getting down into tight places under the hood of a car. I've used these to get into a space between the fender and the headers on my old truck to break the bolts loose. I've also used them under the dash of the truck, getting into the very small areas. I definitely love the size.
- Brightness: This is a good and bad about this set. I'll address the good here. These are bright enough to light up smaller areas. I was able to light up areas under the hood that a normal shop light was not able to light up because I could put the light bar into those tight areas. If you combine the 2 lights, they light up under the hood very well. I actually let my mom use one while she was visiting so she could use it as a reading light. She loved it!
- Light housing: The lights have the ability to stick to metal or hang, which was nice. The magnets are a bit on the weak side, but mine worked great on flat surfaces. I'm restoring an older car so my hood is lacking the heat shielding that newer cars have, making the holding power a lot better. The hook is also available so you have that option as well. The housing is pretty nice, not high quality, but has a good feel to it.
- Durability: I have used these for a variety of purposes. What really impressed me with them is this: I dropped one in my parts washer tank. I got it out after putting the part on the ground and found the botton would not shut off the light. Thinking that it was broken, I placed it on my work bench to work on later, but the next day, I found that it continued to function as if nothing happened. Very impressed with the durability. These are not going to hold up to constant abuse, but for the light duty application, definitely a win.

Cons:
- Brightness: While these are bright, they are not nearly as bright as what a normal shop light would put out. If you use only 1 of these, you'll find yourself holding it while you look at what you need to look at.
- Size: The pictures make these lights seem larger than what they are. I think the size is great for carrying around, but if you need larger lights, these are not it. I think this plays a lot into the brightness as well.
- Build Quality: The quality is good for the price point, but it is not the same quality that you'd find for more expensive brands. The hook feels as though it'd break if you were to quickly pull it from its hanging point, something that mechanics would naturally do if they were working under the hood of a car. I've dropped mine a few times, and they still work, but if you were to step on it, or if something were to drop on it, it'd probably break, especially around the light hinge.
- The red light function is hidden. I don't need the red light function, but if you do use it, you have to know how to turn it on. Hold the power button for a few seconds to activate it. Press again for flashing red, and once more for off.

Here is a quick summary:
These are great lights if you need compact, cheap, and a light that can light up a smaller area. If you need a heavier duty or really bright light, these are a pass for you. I am using mine to get into tight spaces under the hood where a larger light cannot really get to. They have performed great in this type application, combined with my normal shop lights.
These are a great buy for compact, light duty, and tight place applications. I own a total of 6 of these lights and purchased a set for my dad.

This is very decent little light, It is especially good at the price point with two lights included, however, I would avoid the 4 light pack, as that is pretty much a diminishing return.

These were purchased in the middle of a Texas heat wave where I had to fix the wifes' car. However, I am an epileptic that has a sensitivity to direct sunlight and heat in general. Therefore, I work at night. At the time I only had a few harbor freight dollar lights that eat through AAAs like an addict burns through self-respect.

Foremost, these ARE rechargeable, but it is important to know that they run on MINI-USB. It was never claimed otherwise in their product description, but it is important to not assume they run on USB-C. Many of you no longer have MINI-USB cords and they are getting increasingly difficult to find. This also means that these lights will have a shorter service life than had they used USB-B due to the way MINI-USB pulls the charging port out over time. Do not yank the charger out of the light, it will shorten that life even further.

The light modes- the main light bar is a flood style with no hot point. This is great for auto repair. The bar is also thin and able to get into tight spots in order to see. However, the spotlight mode is really dim and almost useless unless being used as a secondary light to reduce shadows from a primary light.

A major plus is that it CAN be used while plugged in. If you have the luxury of a powered tool cart, This can give you a lot more work time at full brightness assuming you can afford extra wires in your work space.

The magnet and hook are quite "meh" If you do not have a thick, very ferrous metal to stick it to, the magnet is mostly adequate to barely keep itself attached when the light is extended to the point of maximum leverage. If you car, suspend it vertically for most stability.

Speaking of suspension, The hook is also just "meh" it does its' job, but is on the thin side which does not inspire confidence that this light will be around for decades. Had it been on a more pricy option, I would avoid whatever brand had the audacity to use it. But as priced, it is kid of hard to fault it as it does work and function as advertised.

The range of motion of the primary like is good. I don't see the average person needing much more flexibility. If you do, this is the wrong type of light in general. You may find more excellence in a borescope style light.

The red light is actually pretty excellent. Bright and clear without being blinding. However the flashing red light seems useless for the demographic this is supposed to be for. It is a work light, not a flashlight. Not a tactical light. It has no pocket clip, so it is not really a hiking or personal light. If you need to flag someone down, I suppose it would work, but even as a "Im walking here, don't run over me" light it isn't going to do well given that lack of a clip. I feel they really should have foregone the flashing red light and invested in a stronger magnet.

It does have that weird "tear up invalid" sticker seen in the pictures, which I thought to simply be an overlooked artifact in editing. No, it is there, and the only thing I can possibly think it is, is some security seal where they wont warranty the light if removed; as if anyone is going to bother.

All in all I say it gets the job done on a budget. But I would certainly keep looking for a more long term solution. Treated well, I am sure they will last awhile. But it is not the kind of light you would expect to keep living through drop after drop onto concrete.

After using this light for some DIY, my family members who were helping really liked it. It's the first panel-style flashlight they've seen, but I expect the format will take off and there will be many more choices in the future.
Having 2 is handy so you can switch when the battery dies. Charging takes an old style cord (micro-B).
Having the switch cycle between the unwanted modes is annoying every time you turn it off, and you have to remember about the tip light or it's easy to leave it on by mistake.
The magnet is not strong enough to reliability hold it on a vertical surface, and it will fall. The hook doesn't let you aim the light downward, and is hard to put back.
It's good to keep around, although you might have a hard time finding it -- why is it fashionable to make flashlights "tactical" all-black, instead of high-vis orange?

The color is nice as well as the design that went into this light.
Comes with charging wire, keep one at home and in truck
Features are flashlight, 2 levels of "shop light"
Bonus SOLID red and flashing red for emergencies.

Didn't realize until it came that its has a hook and really useful magnetic base that actually sticks to metal surfaces like a car hood.

Would def. recommend these.

I have waited some time to write this product review because I was trying to use this work light a little more: overall is a good product, nice bright light, it has 2 settings by pushing the red button on the handle.
The only down side I have found on this work light is that the magnet is not strong enough to hold the light on a metal wall, which is making the light slide down and rotate.
If they will improve the magnet it will be a 5 stars working light.
