77.1  The Singer Curvy 8770 comes with 225 built-in stitches including many block alphabet and number stitches. It also includes a soft cover, an introduction DVD and a number of accessories.  

The 8770 is a fairly feature-rich sewing machine but consumer ratings are not stellar. Owners like that the unit is sturdy and fairly easy to use, however it is a bit on the noisy side and there are sometimes issues with the timing.

There are actually a few Singer Curvy models.  The 8763, the 8770 and the 8780.  We previously reviewed the 8763 and there are some significant differences between the 8763 and the 8770:

- the 8770 is substantially more expensive than the 8763 (often a few hundred dollars)
- the 8770 has 225 stitches, while the 8763 has 30
- the 8770 has block letters and numbers, the 8763 does not
- the 8770 has an LCD control panel, the 8763 does not
- the 8770 has programmable needle up/down, the 8763 does not

Consumer Insights
A thorough analysis of owner comments reveals the following common 8770 likes and dislikes:

PROS
- Sturdy
- Many decorative stitches
- Consistent stitching
- Includes many accessories
- Fairly easy to use
- Well lit sewing area

CONS
- Timing can sometimes go off
- A bit loud
- Can be difficult to sew in a straight line

The timing on this machine can sometimes be an issue. We have read on several occasions that the timing of the machine was off straight out of the box – in which case it had to be shipped back for servicing. In another case the timing would be ok for a while and then it would just go out of whack.

In addition, some folks seem to struggle with the automatic needle threader, while others feel it works well. It is possible that the needle threader is a bit difficult to figure out but once sorted then the threading goes more smoothly.

The tension is another area of consternation, but one helpful owner has pointed out that many of the tension-related problems can be solved simply by ensuring a 15J bobbin is used, NOT a 15 bobbin.

Other insights of note include that the 8770 may struggle sewing through heavy or thick fabrics, that it is a bit noisier than some people expect, and that dealing with Singer customer service can often (not always, but often) take a long time.  You can read more customer reviews on Amazon if you wish.
