A little pricey, but the convenience of having the pre-wound bobins is a joy.  Happy I purchased this set.
CORRECTED REVIEW:
This kit sat unused for several months.  When I opened it, I found that all the thread spools were locked in place, ditto for the bobbins!  Evidently they were incorrectly wound.  There was no way to find the end of the thread -- a short piece that stuck out led to the bottom of the spool and instantly broke the thread.  I have been a home sewer for 50 years -- no novice!  Pricey mistake on my part to purchase this kit and not check it out immediately.
