I use Extend & Climb. Love them. I didn’t like the original Telesteps. I originally had five Telesteps, and they all lasted less than a year. I have nine Extend & Climb, and they all have lasted for five years or more now. Best ladder I’ve ever owned, and very convenient for getting into attics in the beach areas here where the access is in the laundry closet, directly above the real nice washer and dryer.
