I like the low profile and they are easy  to install.. the light produced is not very bright, more of a guide type of light but it is enough to see a rise of a step which is where I chose to install them. I also used them on the wooden handrails at the top and at the bottom of my stairs, both in the front and back of my house. I have only had them for less than a year and have noticed they are losing the ability to produce the light they once produced and now some do not come on at all and others just barely glow. Making the charge to the battery seems to be fading faster than I care for. Price is reasonable but you get what you pay for.
