I haven't used it for six months after using it. Screws and screwdriver are unused. Target animals: Snakes, lizards, turtles, etc. (Ideal for a 60cm aquarium.) Features: Powerful wide heating that spreads downwards. Warms the body to the core. This heater is also ideal for snakes and lizards that may get burned by wrapping around lights. It is ideal for preventing burns. Turtles have their lungs directly under their shells, so heating from above is effective. Other creatures also need to breathe warm air for metabolism, so it is necessary to warm the entire cage. Far infrared rays can moderately warm the air throughout the cage. Misting is possible, making it ideal for creatures that need humidity. Specifications: 32W Size (approx.): Width 40 x Depth 14 x Thickness 2.1cm
