I bought an Exo Terra PT2082 replacement disc from my local pet shop, at twice the price! Unfortunately it hasn't lasted anywhere near as long as the original has, as the metal in the middle of the disc is wearing through! Thankfully I found these at a good price, so I bought three! They fit well and work well but their quality and longevity is questionable, only time will tell.
