Vivarium for small reptile (Tilehurst RG30)

Small vivarium for small creatures. I was advised this size was not suitable for a leopard gecko. I looked after a gecko that arrived in this vivarium. Person never returned to collect the animal or vivarium. I have hence bought a correct size so looking for a new home for this item. Comes with hiding places, heat mat, foilage. It has a hear lamp, but may not be a correct wattage, so please get good advice. Thank you
