I've owned a number of machines over the years and still own 2 cast iron singers, a BL serger and this Esante BLN. I love the BabyLock Esante BLN's quietness, the lighting, the smoothness, consistancy of stitches, ease of use, and the dependability. Top bobbin is a joy! You can pop it in and out easily from the top and see how much bobbin is left! My machine is 10 years old, and I am the second owner for 7 of those years. I did some embroidery early on, but now use it mostly for quilting/repairs/dress making and recently used it to make vinyl luggage for my dog crates to go on top of the roof of my car. Using a 16 needle, going through 2 layers of thick vinyl was fine, 4 layers (with seams) was a bit too much for it. I have never brought it in for servicing, but I will now and have them look at the needle threader and give it a wellness check-up. This is an amazing piece of equipment that is a joy to use. If there is any difficulty with this machine, have a technician look at it - this is truly a trouble-free machine even at 10 years old. I would have no hesitation to purchase this machine used.
