I owned a corded hand mixer about 20 years.  When it died, I never replaced it.  But I do make some sauces and recipes that require blending over heat.  So I was excited about this tool addition.  The mixer is simple to set up and takes a couple hours to charge.  I used it the first time to make a sauce on the cooktop.  It stays fully charged for about 10 minutes.  That was enough time for my purposes but I think it may not be enough for all recipes.  It doesn't seem to have enough umpf for heavy duty mixing.  But one again it worked for my needs.   This isn't a tool I need regularly.  When I do I think it will work perfectly.
