Question: Does this thing hold the load at any height safely? What happens if power is lost?
Document: This is a great hoist -  I use it for winching heavy materials into the attic. Easy to install, east to use. Has a pulley that doubles the lifting power.
This product was delivered timely and is doing the job that we wanted. I'm a licensed Physical Therapist. This Hoist is on a track with a harness so the my young and aging patients can safely practice: walking, explosive jumps, getting up off the floor, climbing ramps and ladders and doing foot work drills without fear of falling.
This is in my shop to raise and lower a 135&#34; projector screen via some cable and pulleys. Works great. Is a little noisy, but in my situation not a true concern. The control pendant chord is a little short in my opinion. Only about 4 ft. I'll extend it for my use. Safety shut off works perfectly and hook and pulley block appear to be more than adequate for the stated load rating.
it works well but is bumpy on the start up each time ..jerks then goes smoothly  wish that could be corrected
Works great. Noisy!
Well-made and functional 120 Volt AC hoist. Actual single-line capacity is 220 lbs. Mine has been in-use about a week with no problems and has very successful. I use it for hoisting my Laser sailboat (about 120 lbs) about 8 feet into the overhead of my garage for storage. $100 is a good price (Harbor Freight has a nearly identical model for sale $100, reg $130). I am very pleased with this hoist/winch, and recommend it.

The Heavy Duty Electric Hoist 441 that I bought was attached to the ceiling securely to help with lifting 40 pound salt bags into the salt reservoir. It worked perfect. The quality of the device was really quite good. I realize that its real value will be whether the device lasts for a period of time, but my impression was that it was well built, safety mechanisms all worked well and were designed appropriately, and its appearance was perfect. While a 25 year old will think this application is nonsense, let that person try to lift 40 pounds waste high when he's 75 or 80.
Need mounts for ceiling but it works good
Its a great piece of equipment makes our job much easier on lifting and moving and easy to use and install
Answer: no
