Singer 4411 Heavy Duty Sewing Machine




The only notable drawback which would keep many seamstresses away from this machine is its inability to modify or inherit the built-in stitches. It has a limited number of built-in features that would not ridicule the novice seamstresses. However, the limited features are enough to keep a professional seamstress glued to the machine for a very long time. The machine is set to give out strong and professional results every time a project is sewn on it. Another probable negative point is its weight. As compared to the other models, Singer failed to cut down on its weight making it difficult to commute with.

Specifications & Features: It has more or less the same features of the above-mentioned Singer models. Not very different from the Singer 4432, the machine can sew at the top speed of 1100 stitches per minute. The metal frame gives the desired stability to the machine. With the help of its heavy-built construction, one can assure himself of getting a skip-free sewing experience. This also lets you have a professional finish to each and every project completed on the machine. It can even surprise you with its quilting abilities.

The features are more than enough to complete any home-based sewing assignment within no amount of time. One of the video on the YouTube shows that the machine could pierce through, not two or three, but 10 layers of denim at one go.

Our Expert Opinion: The robust machine has the ability to sew fast and on a wide range of sewing projects. It is not only versatile but can provide productive results even on the stubborn fabrics like denim and leather. The consistency of the machine along with its speed is guaranteed owing to the powerful motor which is inherited in the machine. The presence of automatic thread cutter gives you the best professional finishes without you running the risk of ripping the thread apart.

One has to be very particular while selecting a sewing table for this machine. Depending on the table you use, the noise of the machine would vary. It is believed to turn out as a noisy machine. Thanks to the presence of a powerful and bigger motor. It may some take time for an intermediate seamstress to get acquainted with the speed of the machine. Although it has a thread cutter, it doesn’t include an automatic threader which is again a pain for the entry-level seamstresses.

Singer 4452 Heavy Duty Sewing Machine

Singer 4452 is believed to have the same metal frame, same features, and similar motor as Singer 4432. The only difference that was noted between these two sister-models is the number of built-in options. Apart from that, there is hardly any difference one can spot between these two heavy-duty machines. The number of built-in stitches is only improved by precisely 9 stitches. Therefore, it hardly makes sense when it is offered as such high prices only on the basis of just 9 extra built-in stitches.

Singer 4452 Heavy Duty Sewing Machine




The machine doesn’t do justice to the price tag at which it is offered. However, it is still as versatile as other Singer models. It can undertake a wide array of projects without tiring off.

Specifications & Features: The machine boasts 20 built-in stitches as compared to the 11 built-in stitches of Singer 4423. The metal frame gives you the freedom to undertake any sewing assignment without having to worry about the machine skipping a stitch or two. One can highly depend on its reliability. The inclusion of thread cutter makes it efficient and time-saving. However, the absence of the automatic needle threader adds to the downfall of the machine.

It comprises a stainless steel bed plate which smoothens your sewing process. It helps the users to feed the fabric in the machine with utmost ease. The machine doesn’t tend to skip any stitches. It can sew at a consistent speed for hours without complaining or be wearing off. We wouldn’t hesitate to call it a workhorse.

Our Expert Opinion: There is simply no point in spending extra bucks just to avail some decorative basic-stitches. It slightly ends on the high side of the price. Its sister-models are much more cost-efficient and user-friendly. One needs to use the 15J bobbins to ensure to that one indulges in sewing effortlessly. The speed of the machine can be adjusted which helps a lot of seamstresses to get a knack for the machine. One needs to use smaller spools in order to sew effortlessly. Bigger spools are prone to cause hiatus to your sewing assignments.

Singer 9960 Quantum Stylist Computerized Portable Sewing Machine

All the stitches can be varied in regards to their sizes. One can even have the desired speed setting according to one’s preferences.

It ensures that the machine doesn’t skip a stitch or two even after sewing for hours at a very high speed. The stainless steel bedplate smoothens the entire feeding process giving you a definitive edge over your sewing projects. The presence of automatic needle threader and cutter are added advantages to the overall efficiency of the machine.

It comprises of 600 built-in stitches and 13 automated buttonhole styles. The number of built-in stitches can take any professional seamstress by surprise. We doubt that all the 600 stitches might come in use in an entire lifespan. Apart from the built-in stitches, it boasts as many as 5 font styles for undertaking monogramming projects. One can edit the stitch on the screen before having to trace it on the fabric.

Our Expert Opinion: It is undoubtedly one of the best machines that have come through the ranks of Singer. The computerized sewing machine is stuffed with features, some of which one would hardly ever use. It has all the features required to suffice the needs of seamstresses of all levels.

Apart from that, one can even adjust the width and the length of the stitch with the help of a designated lever inherited on the machine.

Our Expert Opinion: It is an easy-to-use sewing machine capable of undertaking almost all kind of sewing projects. However, it is not only its simplicity that attracts the users, but also the productivity that the machine is able to produce.
