Comments about Optimus Terra Pot Lifter:

From the description, I thought this was aluminum. I was surprised when it arrived to find its actually plastic. That's why I deducted stars as plastic might not be acceptable to some.
On the positive side, this is lighter weight than an aluminum one and should be kinder to pots that have a non-stick coating.
Time will tell how durable the plastic is, but so far its done the job.
