I hate mine. Got it for $600 2 years ago. Used it total of 3 hours. It's been back in the box under the bed since then. Its' become the nightly toe-stubber when I get in bed.
Reasons: area is too small to work on; weight of quilt pulls too much; takes forever to set up and take off; it's higher than machine bed; makes machine throat even more crowded when quilt is rolled under there. I could go on but you get my drift.
In fairness, there are other QB members who like it. Please, please try it out with a LARGE quilted item, not the small sample item they use in the store. Of course a small item works!!
If you lived near me you could have mine!!
Please try it and let me know if it works for you--maybe it's just me and I'm doing something wrong (which wouldn't be the first time LOL)
