That may be a decent unit - and while it would be pretty good at repeating bends if you let it run it's full course, as bdkw1 said, repeating less than 90 bends would take some work.

BUT, with a little perseverance, you can probably learn to do under 90 bends and repeat them.

Use something like a bent (to the angle desired) piece of TIG filler wire and hold it against the tube as it's being bent (making sure you keep your fingers clear of anything that might want to eat or remove them) until the filler wire's bend matches the bend you're putting in the tube.

Bang for the buck, that may not be a bad unit at all.

Harbor Freight bender works exceptionally well as a boat anchor, but not much else.
