I initially like this product.  It seems to be of descent quality especially for the price.  I hooked it up and ran it for about 15 minutes while just sitting in my truck and it got pretty warm.  The only thing I am concerned about is if it blows fuses after 30 minutes of use while driving my truck.  I will probably run another line for it directly off the battery.  Once again I urge you to think about what you are purchasing and how much you will be using it.  It is not costly enough for me to trouble myself with sending it back if not satisfied and I took this in to consideration when purchasing.  It is very inexpensive and I do not intend to be using it on a daily basis or I would not have purchased it.  Use your good sense.
