Advantages: Easy installation. Literally a switch. If it is not aligned, the light will flash. Comes with a magnetic base which I haven't used yet. Comes with a carry bag with ample padding. Cons: When used outdoors, this must be done in the evening or at night. Judging by the ratings, this is common for this level. There are models that are twice as expensive that advertise daylight visibility. I would recommend this level and Huepar seems to be the transition level.
