This line from the description is not a good sign ...
- 2 Frames Measuring 17" Tall By 11" Wide
Standard frames are 17 3/4" across the end bars, plus another 1.25" to accommodate the topbar 'ears', for an overall length of 19". That could
just be an error in the description, or maybe not.
Keep in mind that this two frame extractor is almost certainly tangential style, so you will load two frames, extract, flip the frames and then extract the other side of those same frames.
"Lifetime warranty" sounds good, but is it believable
? Are they really going to replace the motor for free if it craps out? What are the terms of that - do you have to pay to ship the entire extractor back to them for evaluation? What about return shipping?
