PROS
- Headband is quite comfortable - Comes nicely packaged, with a plastic box with a clear top for the lenses
CONS
- Doesn't come with any AAA batteries, so you'll have to supply your own - The 2 LEDs are not very bright. It might be ok for closeup work, but don't expect much distance
I've been trying various head-mounted magnifiers for doing closeup work like soldering, and have found the ones with solid bands to be quite uncomfortable. Also, unless you buy a quite expensive one, they have a very short focal point, i.e., you have to be right up to the work, otherwise, they won't focus. This head mounted magnifier comes with a set of 5 lenses that snap into the light part, so you can combine them, starting at 1x. As the number of times magnification increases, the focal point gets closer and closer, i.e., at high magnification, you have to be pretty close to the work. So, this item allows you some flexibility, i.e., if you are reading, you might use the 1.5x and be able to read from some distance, whereas if you're doing closeup work and want higher magnification, you can choose the lens. The lenses have their power moded into one "arm" of the lenses, and you click the lenses into a rotatable clip. The head lamp also pivots up and down, but I found that the 2 LEDs are pretty dim. They might be ok, but don't expect them to light up anything more than a close distance. As mentioned in the "Pros", the lenses come in a clear-topped, flip-lid plastic box, so you can keep them organized. It takes 3 AAA batteries. Nimh seems to work ok. I really don't like AAA, but I've found that if you have 2 AAA dummy batteries, you can sometimes use those with a 1x10440 Li-ion battery, so you only have to recharge one battery. Note that the way the battery contacts are designed in the battery box, batteries MUST have nipple-type tops, as the contacts, including the positive contacts, are kind of recessed pretty deep. I've only had this for one day, so I don't know what the durability will be, but overall, these are not bad, esp. if you have another light source.

PROS
- Fits perfectly with an Ultrafire S5
This is a good fit, basically, a drop-in replacement for the Ultrafire S5 lens, if anyone is interested in an optical lens vs. a reflector. The nice thing about this combo is that the S5 has a retaining ring that holds the reflector in, so if you switch to using this optical lens, you can just screw the retaining ring in until the front of the optical lens is snug up against the front. You may be able to/want to actually remove the lens as it looks like the front part of the S5 head would hold the optical lens in. Comparing the beams (original reflector vs. optical lens), the beam with the optical lens is somewhat wider. Probably the 30 degree 20mm version would work as well, and provide more flood for the S5, if desired, so you have some drop-in options for beam, reflector, 15 degree optical, or 30 degree optical.

PROS
- Comes with a nice case/box
CONS
- Probably (definitely) not 1600 mAh capacity
Received these batteries, in a small plastic box/case. Voltages out of the box were ~3.98V. I charged them and then tested in my lights. Based on how long it took to fully charge these, I seriously doubt if these batteries have 1600 mAh capacity. I'd guess that they're probably less than 1000 mAh.

PROS
- Large assortment of shapes - The tips appear to hold up well under use
CONS
- Cover is not attached
This set of grinding tips is kind of an amazing value. I was kind of worried that the tips would not stand up to use, but I've used them in my Dremel, and expecially the pointed ones, to enlarge and extend holes in a number of aluminum pills when modding lights, and they're still going strong. For the price, it's a heck of a deal! Recommended!

PROS
- Cheap
CONS
- Cheap - what I mean is that the blades are REALLY thin and weak. - Case is easily damaged
I received what appeared to be a used knife set (retaped by someone), with a broken hinge and latch, but that aside, the blades that come with this set are terrible. Very thin and weak. I really wouldn't recommend this set to anyone.
