I purchased a Casio EXilim model EX-Z300 last July. It worked well but the date search function never worked. When attempting to search for photos by date, the camera freezes and power must be shut-off. Why didn't I return it or get it repaired? It was summer and I needed the camera and couldn't wait weeks for the repairs. It takes nice photos but I regret purchasing it. Another problem is the Best Shot settings have to be re-set after turning power-off. The camera has nice features but has several problems.
