Great service. The sewing machine arrived the day after I ordered and the free gift of scissors was a nice touch. My wife loves it and is looking forward to making some new chair covers with it.

Wouldn't dream of buying anything other than a Singer, my mum was a dressmaker & Singer demonstrator back in the 1950's! I was sad to say goodbye to my previous Singer having sewn our daughter's wedding dress, my own outfit, bridesmaids dresses etc for family weddings. But I'm really pleased with my new heavy duty machine which glides effortlessly through 4 layers of denim, brilliant. No complaint with foot pedal either, as some have mentioned, however I always sew barefoot, maybe that aids control? Great value for money, thank you.

Fast and efficient delivery service. Excellent machine from a long standing company. Look forward to many years of sewing.
-
Great online service for letting me know when this product was back in stock and then the delivery was very quick and securely packaged.
This is a fantasticly strong machine and it just chugs through heavy material. Great build quality - wish I knew about it years ago!
Some great Singer videos o YouTube for this product too!

When I first took this machine out of the box, I felt disheartened as it was so light. I didn't think it would be powerful enough for what I want.
Wow, how wrong was I. It might be light, but its a powerful, smooth operating sewing machine.
Highly recommend. -
My old singer 'died' and i decided to order a better heavier duty one. I ordered on Friday afternoon and it was delivered just after lunch on Sunday. Amazing service! The new machine is excellent and surprisingly easier to use than the old basic one. Delighted with it.
-
Absolutely love this machine, stitches really well and is a great buy.
-
Extremely pleased as I originally ordered one on amazon only to find it was an import and had to send it back. This exact machine ended up costing less and only draw back I find is the foot could lift a bit higher to allow thicker materials.
-
Delighted with the delivery time, especially as this was during the early days of the Covid-19 lockdown! I am completely new to sewing but am slowly getting familiar with my new Singer 4423 and am happy so far......sew far, sew good!

I have recently received delivery of my Heavy Duty Sewing Machine and I am very pleased with the results so far. Repairing Jeans has never been easier as the machine effortlessly sews over thick seams. Like others I am also finding the automatic needle threader tricky to get used too. Hopefully I will get the hang of this soon. Delivery was on time and very helpfully gave us and hour window when to expect the arrival of the machine.
