Sorry, but...

(Customer's Reviews)

This item wasn't my cup of tea. I'm sure others would find it fine. It just seemed a little fragile to me. Plus, given the set up of my bending iron (which I like a lot, side-review) it would not stay put. The fine folk at Stew Mac were incredibly helpful, even sent a new one while I still had the other, but I could not make this work for me. Your mileage may vary. I'll take a moment to praise the customer service again. It was excellent and the reason I'll be sticking with Stew for other purchases.


A required tool

(Customer's Reviews)

I bought the bending iron and this thermometer at the same time. I can't really see getting one without the other. This surface thermometer saves me the grief of trying to bend sides before the iron is hot enough and prevents scorching by preventing the iron from being set too high. Delicate but accurate. Just treat it like the fine measuring tool it is and you'll be fine. Looks like it would last a lifetime if treated right and accurate as you could ever hope for.


It does the job.

As a beginner at guitar repair I was nervous about removing the bridge on the guitar. I purchased the Bridge Heater and Fingerboard Iron along with the Surface Thermometer and was very careful to maintain the proper temperature. Very slowly, carefully, and methodically I was able to remove the bridge and all went well. It does the job but you must be very patient.
