GEX EXOTERRA Timer Thermo RTT-1 by GEX Exoterra Temperature and Lighting Control with Timer Function and Power Outage Backup ◎ Box included ◎ Instruction manual included I purchased this new and used it for about 2 months. Due to a lamp (light bulb) failure during use, it is currently unresponsive even when powered on. The cause is unknown, so I will treat it as a junk item. Recommended for those who can repair it or use it for parts. Please purchase only if you understand the condition. Please note that we do not accept returns or complaints.
