Bought a curved stair lift and have had it about 3 months now. A somewhat long process as they had to send a tech to measure our stair case, make a CAD for our approval, then custom manufacture the unit for our home. The actual lift arrived about 30 days after we placed the order and they showed up a week later to install it.
Have to say it works perfect and we can now relax knowing our mother will not fall down the stairs. Outstanding product and would do it again.
