Good for some quilting

Good Value, Easy To Use

This machine is my first Singer purchase and I found it was a good value and easy to use. I recommend it for beginning/intermediate sewers. I've used this machine continually, short of it's 2-year purchase, making a number of wheelchair bags, lap quilts and miscellaneous craft items.

Cons: Durability: I bent the whole sewing machine shaft when sewing a well padded Quilt and using the Even/Walking Foot for the first time. I'm not sure what happened except I heard an awful sound. The zig-zag operation works but due to the bent shaft the needle hits the pressure foot as well as other feet do not even attach now. I was so bummed out. As my charity work continues I needed an immediate replacement machine and have purchased the 7470 Confidence hoping for better results.

To oil of not to oil?

Good Value

To oil or not to oil? That seems to be the question - which nobody answers. Why not write replies to the reviews? Would that not be of more value than just publishing reviews? Yes, the machine is rather noisy, which is okay if one doesn’t worry about it and keep wondering if it should not be oiled? Like so many reviewers I myself also have a 60/70 year old Singer, still in working order and would like to beat that record. So, if it needs oiling, like sewing machines usually do, I would like to know about it. Also wish there were a thing-y with which the empty bobbin can be lifted from the bobbin case when it is time to change the bobbin. And ah! Threading the needle … if only, if only I could manage that! But I have a notion the problem here lies with me, not with the machine, but with me not properly knowing how to do it. Love the speed, love the heavy duty, love the fancy stitches, love the machine as a whole. Especially as it was a gift from my son – I can feel the love every time I use it!

Nice machine, but...

Good Value, Great Features, Easy To Use

For the most part these are wonderful machines. I had purchased 6 for the sewing room at work. Three had to be returned to the store for various reasons. On two of them, the needle threaders didn't work. On the other one, the needle position was incorrect. It was too set too far forward and the needle was hitting the presser foot as it sewed and broke every needle until we figured out what the problem was. Of the remaining machines, two can no longer use the automatic needle threaders. For some reason they just don't work any more. I feel the "free-arm" for cuffs or other circular projects is too wide and doesn't accommodate use for smaller sized garments. The sewing bed is a bit shallow.

Poor Quality

The first few months I used this machine is good but I also noticed a big problem with the bobbin and its always jamming up, so very frustrated with this machine, its not heavy duty after all. Threads keep on breaking whatever adjustment I do. Singer you need to improve this model. no. or just cancel it from your line of product. This machine is not even a year when I bought it but its already broken.

Very Poor Instructions

I really like the Singer Model 4423 because it works the way I want and has handled all fabrics I have worked with thus far. Due to weight loss, I am altering many articles of clothing, and am impressed with the consistent quality of the sewing.

Some history: This is my second Singer: the one I purchased in ~1972 had a chronic problem of messing up the thread in the bobbin area. Even my mother who could take a Singer apart and fix anything, could not fix this one. I finally only used it for quick jobs; and when really sewing used her ancient Singer--electric, but very basic, and sturdy and reliable as anything ever made by man. Probably circa 1940's model. And my grandmother had one earlier, also sturdy and reliable--the treadle version of I do not know what date. Neither of them EVER had a problem with a Singer.

However, there are a few things that I do not like about this purchase: First, the needle threader gizmo is a total waste of time for me. It takes me 6+ attempts to make it work and repeated re-threading of it, while I can generally thread the needle the "old-fashioned way" in one or two tries.

Second, the instructions are pictures that lack detail in key places, i.e. threading for bobbin winding pictures do not show where exactly on the tension thing the thread goes. I figured it out via trial and error.

Third, the picture instructions for inserting the bobbin and pulling the thread through contains a flat-out wrong thing: if you close the bobbin cover as it shows before pulling the thread through to the top, then it does not work. Again trial and error worked and when I left the cover off, no more problem. Just put it on after thread is pulled through.

I think Singer Co. needs to improve and include more detailed instructions with each machine (sewers are not illiterate, some word instructions would be very helpful). Good instructions would be in line with the great old standards the company once had.
