Walking pad G1 or X21

looking for a new compact treadmill for my house as my mobvoi from Amazon has died after 1.5years of use. I am wondering if anyone who has had a walking pad G1 or X21 for longer than a year and could review them. I am open to other options as well. I ussually switch between walking at 3mph and light running around 6-6.5mph. I use my treadmill a minimum of 5 days a week for an hour a day.
