No CD e

Tough to see in low light. Would have preferred brighter but does what I needed. Two for two rooms good price. Wish they had a little more weight to them as I walk by and they are easy to knock over. I might try attaching to a base overall nice for the price and speedy delivery.

Small Wonder

Newly arrived so still observing performance. Has battery installed for immediate start. Could use backlighting since it does not illuminate after dark.
