Bests & Worsts Reviews from Amazon

I recently purchased the Brother cs6000i for $159 on Amazon. I was somewhat leary of making the purchase because of all the people who experienced tension difficulties. After reading all the reviews on this(and other sites) it seemed that the vast majority of people were more than happy with the machine once they were able to solve their tension problems (by using metal bobbins) or threading the machine correctly. I mistakenly assummed that I would not have such problems(because I would read the manual, etc, etc.). Originally I had some difficulty, but after reading someone's comment on a quilting site, realized I had the bobbin in wrong. It needs to feed the thread from the left, not the right (clearly shown in manual). What do you know, the machine worked much better and I worked on adjusting the tension for specific material, etc. All was going smoothly until I changed my bobbin. Suddenly, I was back to the original problem of loose threads on the top and bottom from tension problems, but I had made sure I inserted the bobbin correctly, so I was majorly frustrated. I hit the internet -- I watched videos, I read reviews and it seems I needed to go out and get metal bobbins. I was frustated because I had purchased two extra packages of clear bobbins and didn't want to have to throw them out for metal bobbins. I prefer the clear so I can see how much thread is left on the bobbbin. I was going to call Brother and ask what step I might be missing when I checked their FAQ section for my machine. After reading a bunch of things that didn't help, I read the "how to thread a bobbin" section. I saw a diagram that indicates there is a small wire bobbin tension-adjusting spring that the bobbin thread needs engage in....here is the key: when you drop in the bobbin, put your index finger on the bobbin to hold it still and then start to feed the thread around the guide pulling it a bit straight up until you hear and feel a small click -- once the thread is engaged in the spring, continue threading around the guide and I am betting your tension problems will be over! It would be nice if Brother would update their manual to include the information about the tension-adjusting spring since this is causing such an huge issue for people. I am glad I can use the plastic bobbins and bet that others that have switched to metal would be able to as well. Once I felt the "click", I knew I never had engaged it previously. I tried every single stitch and each one looked exactly like the example -- clean and sharp, much nicer that my previous stitches that I had thought were nice! All those hassles......................gone! Best wishes, I just love this machine **NOW**, the feet are so easy to change and threading is a snap! (and a click!)
