Summary:
I've had mine for on 3 months and well pleased with them. Mine HAVE NOT cracked - the lenses or the nose piece - you've got to insert the base of the lense in the nose retainer area' first, then the top section of the lense.
Upon washing: 'em the top section out 1st etc...

Surely people aren't that stupid ? They're only plastic NOT metal.

Also, I cut the very top of the noserubber piece for a custom fit.

Strengths:
Active + lens - Clarity on medium days virtually an all rounder and destroys glare at night from cars !

Weaknesses:
The Active 4000 lense shields you on bright days yet still keeps you sharp.

Fails on ULTRA bright days.

Summary:
So far I have really enjoyed these glasses for recreational cycling and road racing. I have not used them for other sports though I considered buying darker/polarized lenses for skiing and sea kayaking.

Strengths:
Optical clarity, low light contrast, comfort, fit, good ventilation in a wet and foggy climate, and good looks. The single lense is easier to swap out on the go than two separate ones.

Weaknesses:
I have noticed small cracks develop in the lenses at the bridge but they have not broken completely.

Summary:
Functionality wise the design is great. Very light, lenses do not fog at all, the frame does not slip off while on riding or running, great optics.
As far as durability... lenses need some improvement. Cracks started to appear about a month after I bought them with my first lenses breaking at about 6 months. The second lenses lasted me only about 4 months. In addition, Briko does not seem to sell lenses outside of the Sprinter kits.
As far as customer service or support... there isn't any. The only contact I found was through Brikos sales e-mail address, and they will not respond to your e-mails.
I would not recommend you spend your money on this product or any other Sprinter kit.

Strengths:
No fog, no slip, great optics, low weight

Weaknesses:
THEY DON'T LAST... Brikos non existent customer service (or imposible to find)

Strengths:
Strong Frame.

Weaknesses:
Weak lenses.

Summary:
Getting to the age where I need glasses I purchased the Briko Klip, which is similar to the 1's but has a insert for prescription lenses. So far I've not had the cracking problem mentioned in other reviews. These glasses are very light. comfortable and never fog. Even in 90 degree/ 90% humidity days they stay clear. I've had Oakley M frames and had fog problems while the Briko's just don't fog no matter what the weather.

Strengths:
Never fog, very light weight and comfortable even with my prescription inserts. Good clarity. Lense changing is pretty easy, but I can see how the center of the lense can crack if its not done correctly. Lastly my son thinks their cool.

Weaknesses:
Their not Oakley M's so if you want to be a Lance Armstrong wannabe its the wrong image.
