Crosswalk CR Treadmill
"The Proform Crosswalk CR Treadmill is a large step up the
pricing ladder from the 400e reviewed above, and I don't think
it's worth the money."
Proform Crosswalk CR has an under powered motor, and a small
treadbelt of only 18" x 50". There are bargains to be
had in the under $700 treadmill market, but the Crosswalk CR is
not one of them." - https://www.trainersecrets.com/treadmill/proform/proform_crosswalk_treadmill_review.htm
is one review on Proform Treadmills:
is the largest seller of treadmills in the world. They focus on
budget models and sell through mass merchants, large sporting
good chains and the home shopping networks. ProForm is owned by
Icon Fitness. In addition to selling ProForm fitness equipment,
they also sell Weslo, Nordic Track, Reebok, Image and
HealthRider. ProForm along with the other Icon brands dominate
the sub $1,000 market."
"We know that ProForm offers an attractive price, with
treadmills selling as low as $400. The question is, are they a
good value? From strictly a price perspective they are an
excellent value. When you factor in durability and maintenance,
their value may come into question....."
