Yes, I have one and I like it. If you are opening seams to reduce bulk, it's so handy to have.It's great for any small area where a large iron would be too big.
As far as not getting hot enough,oh boy, mine sure was hot enough!!! This topic reminds me, before I use it again, I should buy some heat resistant thimbles. Darn, where did I see them? Oh, well, I guess I will be doing some web searching. I bought the mini iron to use when making stained glass quilt projects. I haven't made the stained glass quilt projects, but I use it for other projects. If your Mom is making doll clothes I would think she would find it very useful,just as I have. My Dad always said, "Having the right tools for the job makes life so much easier". Dad was right.
