Really effective and quite bright but the battery compartment is ridiculously tight to get the batteries into.
I could not do it myself so I had to wait for my husband to do it and he has had to force them in so god only know what we are going to do when they need changing.
It is the same on the single light as I have bought that too.
The glass is of a decent thickness which I was pleasantly surprised about so they do not look like they will break too easily.
I just hope they will survive the rain etc being outside - but it does say they are for outside so fingers crossed.
Just a pity they are not remote control and you have to physically turn them on and off as that is a pain, maybe that is something for them to think about on the upgrade?
