Pros: 1) bought this set solely because of the rear lights, which in principle is the best there is in this set
2) The front light can be used only as a gauge, the light from the almost non-existent
3) in the light of joy just blinking flashlight mode, which allows you to identify yourself on the road
4) in the presence of a rear lamp ??????? 5 modes of operation: just burn, all LEDs blink once, blink poperemenke 5 different ways) to work on before ispollzuetsya akuumulyatora 3 AAA, 2 AA akuumulyatora ago. Perhaps when using alkaline batteries, the brightness of the front light will be more, but not so as to use it as a front light to ride. 6) two 800 mah AAA batteries for the rear light enough for about a week normal use, that is a good indicator. 7) once removed a bicycle (a flight through the steering wheel), in rezultate taillights got a good shot and otletela red cap, a lamp was in the puddle, after I assembled it, did not want to be included. After 5 minutes, apparently dried up and running.

Cons: front light used to illuminate the road can not be of the 3 sets of rear lamp did not work on a light-emitting diodes, which was written with photographed in DX, DX staff then sent two new sets, waiting for

Other Thoughts:

Bottomline: best rear light

Pros: It is easy to mount this set to your bicycle. Your ride will be much safer. These lights are bright enough and are perfect for the casual riding. Value for money is excellent and aren't likely to be stolen if you don't remove them from the bicycle. However it is very easy to easy to remove them from your bike when not in use. Front light have constant beam and flashing mode. The rear has more different combinations. Both front and rear uses same AAA batteries and they last a long time.

Cons: Not extremely bright, could be brighter, however you will be seen and this is the main purpose.
Plastic is cheap. Be careful when disconnecting the lights using the quick release.

Other Thoughts: Actuality it is 6-LED Front and 5-LED Rear, but who cares ;-)

Bottomline: Good value for money. On the other hand it is very basic lights. It satisfies legislation for lighting on bicycles, but there are some better looking / brighter / nicer… light on the market … and they cost more.

Pros: Cheap. Like all DX Stuff.
The lights are bright, and last a long time on a set of batteries. Good to have both steady and blinking modes.

Cons: Front light broke when I hit a bump, after only a couple of weeks. It wasn't even that big of a bump. The light still works, but doesn't mount anymore.
Back light has too many modes, and turns on easily in a bag or pocket.
In general, they are built poorly.

Other Thoughts:

Bottomline: Weak plastic and buttons destroy an otherwise great deal. Only buy this if you are REALLY gentile with your stuff (that is, ride a plush hybrid/mtb on smooth roads). The front light will break with normal use on any city streets.

Pros: - Very cheap, it cost much more where I live.
- You get both front & back lights, which is nice.
- You can choose from 2 options for the white fron light - on or blinking.
- you can choose from many more for the rear red light.
- works with leds, which can give you longer battery life.
- Can easily disconnect the lights from the mount ring if needed.

Cons: - Plastic is very cheap.
- When disconnecting the lights from the mount ring using the quick release, you need to be very careful not to break the plastic quick release knob. it doesn't seem it will really hold a lot of mounting/dismounting operations.
On of my front lights quick release knobs broke on the first day...
- the mounting ring is pretty small.
I got 2 sets, for my girlfriend bikes it was OK, but for my bikes which are a little bigger, the ring was to small for fixing the back light on the chair stand, and the from ring screw was too short to fix it well, I had to by a separate longer screw to make it work.

Other Thoughts: Good price, I would prefer to pay a bit more and get a better plastic quality, in the quick release knobs at least..

Bottomline: Well, if it suites you, get it.
I don't know if the expensive ones really have better quality then this one.
