These are awesome for some glow rounds or backyard action ! I've baught a few of these and have noticed unless your always using these , remove batteries from both remote and pucks so your not buying batteries constantly. 

This is a fun little light to add to any game. I have it on my portable basket I bring camping and it adds a fun flair to the late night putting games. I have only had it for a month so I cannot speak for the long term durability, but it survived my most recent camping trip without a scratch and I am not light on my gear. 

I've bought 5 of these now and they do a good job lighting up the baskets for night rounds.  My only complaints are sometimes if the light module gets bumped the batteries will jostle just enough to power off the light.  Then we'll have to unscrew the cap and reseat the batteries.  Second it would be really nice to have these using rechargeable battery packs instead of just 3 AAA's.  Would love to be able to just plug these into a charger after a round or two instead of constantly replacing batteries.  Granted I do play a lot of night rounds through the winter after work so these get used pretty heavily.
