  • Stitch quality
  • Speed
  • Ease of use
  • Maintenance
Needs lots of help – able to sew a straight seam but unfamiliar with most sewing techniques; needs assistance and instruction on basic sewing techniques.
Competent – can make different clothing items without assistance or guidance, but not good enough to sew intricate projects or to sew without a pattern.
Expert – can sew anything without instruction or assistance; possesses an expansive knowledge of sewing techniques and terminology.

When I read that the Husqvarna/Viking Opal had received the Consumers’ Digest Best Buy award, I simply could not wait to review it. That opportunity finally arrived and I immediately took advantage of the opportunity to review it.

Viking Opal 670

Viking Opal 670

The Opal comes in two different models, the 670 and the 650. On the day of my visit, I had an opportunity to review the 670.


  • Good transitional machine for people moving up from mechanical to computerized sewing


  • Fewer features and accessories than many other computerized sewing machines in its price range

At A Glance

One look at the Husqvarna/Viking Opal 670 is all it takes to recognize that this machine is somewhat different from all the other machines in the rather extensive line of Husqvarna/Viking computerized sewing machines.

The machine itself is a little smaller and the LCD screen is smaller. Upon closer examination, however, it is obvious that most of the other standard features found on Husqvarna/Viking sewing machines are right there at your fingertips.

Working on the Husqvarna/Viking Opal 670

Simple threading on-board guides

On board graphic guides make winding the bobbin and threading the Husqvarna/Viking Opal is as simple as can be.

If you are accustomed to a mechanical sewing machine, there may be a slight learning curve when it comes to the stitch selection process.

The stitch selection guide beneath the lid is very helpful. The first thing you must do, however, is to go into the stitch/font selection menu to identify the stitch category you want to choose from and then dial up the desired stitch number.

As soon as a stitch is selected, the Sewing Advisor pops up on the LCD touch screen. It not only shows you a graphic display of the stitch, it will also tell you which presser foot to use and helps you determine the best stitch length and width that would work best for your specific sewing project.

The fix function assures that each seam is locked at the beginning and end points. The speed control mechanism is operated by touch, not by a slider like on many other machines.

The Husqvarna/Viking 670 runs quietly and steady. The construction is solid and there is virtually no vibration whatsoever, even when sewing at the highest speed setting.

The stitch quality is good. Stitches are tight and secure. Although I can’t pinpoint the specific reason, I wasn’t too impressed by the final look of the decorative stitches.

Tying Off The Loose Ends

When it is all said and done, it’s easy to see how the Husqvarna Viking Opal won the Consumer’s Digest Best Buy Award. In my opinion, however, there are a few things to be desired with this machine. That does not mean it’s not a good buy.

Personally, I would like to see the stitch selection process a little less complicated and the stitch quality a little better. The Opal is a solid machine that runs quietly, has no vibration and once you get the hang of it, does a great job.

I believe the Opal is a good choice for those who are moving from a mechanical to a computerized sewing machine. There is, as I said earlier in this review, a learning curve, which is to be expected anytime you step up to a more complex piece of machinery.

As a rule, I hesitate to recommend computerized sewing machines for use by beginners. The Opal may be one of those exceptions.

Too many options and features to choose from

Too many options and features to choose from

Not only is it a good transitional machine for those who have worked almost exclusively on mechanical sewing machines, it could very well be an ideal choice for the older beginner who wants to dive into the deep end of the pool.

Someone with even a little bit of experienced on computerized sewing machines will be able to work on the Opal with just the owner’s manual to guide them.

On the other hand, if you have never worked on a computerized machine before and are interested in purchasing an Opal, make sure your dealer offers tutorials.

The 670 has more to offer than the 650, and the price reflects that. For the $500 difference, I think the beginner or anyone who has worked on a mechanical machine for a number of years might be happy with the less costly model.

The additional features are wonderful and a great advantage for the experienced home sewer. I sometimes wonder, though, if a beginner or a seasoned home sewer who has never worked on a computerized machine might be overwhelmed by suddenly having too many options and features to choose from.


  1. On Oct 23, 2013 I purchased the Opal 670. Brought it home and opened the box the next day to use the machine. The machine clanked, and clunked, the cutter didn’t work and the top tread kept bird nesting on top of the bobbin. Took it back and another Opal 670 was given to me. Take it home and a few days later I take it out of the box and set up to sew. The machine sounded like a Mack Truck changing gears.

    Not wanting to drive 50 miles back to where I purchased the machine it was taken to a Viking Repair shop. 2 weeks later the machine comes home.

    I feel that the Opal is not a quality machine. The repair shop stated they are starting to see more of these machine come in for repairs before you get a chance to sew on it.

  2. I am in love with this machine! I was using a 20 year old Brother machine before I purchased the Opal 670. I didn’t know what I was missing! This machine is a dream. I find it very easy to use. And I find the stitching is beautiful. And mine is quiet and works like a champ. You will not regret this purchase!

  3. You mentioned that the Opal 670 has fewer features and accessories than its counterparts in the same price range – can you give a few examples for comparison? Thank you.

  4. The jury is still out on this machine as far as I am concerned. I have had quite a few incidents of machine overload while doing routine tasks. The thread cutter works about half the time. I took it back to the dealer concerning both these issues. They were unable to duplicate the problems but did replace the thread cutting part. I still continue to have the same problems. Now the tension is off when sewing denim and I have not been able to adjust it to right the tension. I’ve had it about 10 months and am about to send it back to the dealer, 125 miles one way. Not convenient! For almost $1000 I expected a more reliable machine. On the other hand. . . The many decorating stitches are fun, needle threader is helpful, but the perks are, so far, way outweighed by the problems.
