Rick Dyerwrote a review of Petzl MYO RXP Headlamp on August 16, 2010
This is a great lamp. It is not perfect, but it is very, very good.The lowest brightness setting is still brighter than most standard 3AAA cell LED lights out there, which I'm sure we all have owned at one point in time. The brightest setting is very bright, especially with the diffuser down where the lamp is in "spot" mode.I've used this lamp since February in all conditions from alpine starts in the mountains to midnight trail runs, to after dark, rainy night runs on the road after work and kids have settled down. Even with oncoming traffic blasting me with their brights, I can still see the road in front of me with this light.I was worried at first about the battery compartment not being entirely sealed, but it functions fine during heavy rain.I hesitate to give it 5 stars because due to the battery compartment being so heavy, I need to occasionally tighten the straps mid run to prevent the unit from slipping out of place. Other than that little complaint, the unit is flawless in my eyes.
