Pros: Really sturdy rubber.
Tighter back ring than western brands (this can be seen as a plus, since the ring can act like a penis ring, making the erection last longer)
No lubrication.

Cons: Unknown storage conditions.
Over all slightly smaller than western condoms.

Other Thoughts: DX brand
flattened width: 52mm
width of rubber ring: 50mm
length: 186mm
RFSU Swedish brand:
flattened width: 53mm
width of rubber ring: 52mm
length: 199mm
These are measurements made by me with no pre-defined system of measurments, they should not be seen as much more than a comparison between the basic size of Swedish RFSU condoms (wich are of a very uniform size for the "standard size" ones) and the condoms made by this chinese company, wich i suppose are of similarly uniform size.

Bottomline: I would probably trust these condoms as much as any "made in asia" comdoms regardless of brand (RFSU are made in Sweden, to a set of specifications much higher than the EU norm)...
but even if you do not, lots of people use condoms with steady partners where the purpouse is more of a "sperm collector" than anything else. Or you can just use them as party balloons...
