SH did repair the beard trimmer, but it is not a permanent repair. Turns out the soldering iron is not quite up to par, so he had to tape the battery to the mount to keep it there (my idea) and then solder it for the contact. Something about how the soldering iron couldn't get hot enough to melt the - stuff - and all that technical fixit guy blah blah blah. He did trim his beard and will get a few more trims, but this is not permanent.
SH: This isn't going to last.
Me: Uh oh.
SH: I might have to buy a new one.
Me: But I thought you were going to shave the beard off because of the scratchy issue.
SH: No. I might have to get a new soldering iron. I've had this one since high school.
Me: Oh. Well. That's OK, then.
SH: I guess I'll have to go to Menards. [He was happy about that, I could tell.]
Me: Should you look at Consumer Reports first? You do have a tendency to cheap out sometimes.*
SH: It's a SOLDERING IRON. Consumer Reports doesn't review things like that.
* Well, he does. Now he believes me that the generic brand isn't always better on things like oh say, Q-Tips. Sometimes things are not better because they are more expensive, they are more expensive because they are better. Sayeth the gold digger. Love ya, honey!
