No-Solder chip and laser?

[SilentHill]

Could anyone enlighten me as to whether or not there's proof that the No-Solder chip - also known as the RMOD I believe - does or does not interfere with the laser strength on the PS2. I've got one and I've seen contrary opinions about whether or not it affects the laser - I thought it just over-rode the eject switch. I'm thinking of getting a flip-top case which presumably would not affect the laser but if the No-Solder does nothing to the laser there's not much point.
