I got two solar lights from Sola Lite about two years ago - one for my office and one for my hallway and I love them. I haven't had any problems and they make my house a lot brighter.
If you get a solar lite from them I would suggest having them go ahead and install it. It's worth the expense. I debated hiring someone cheaper to install it but am glad I didn't. There was an issue with my house and it ended up being a lot of work to install the lights. These guys knew what they were doing and it was done right. I know if someone who didn't know the product tried to do it then it would have been messed up.
