It was just what I needed AND shipping to Hawaii was the same as shipping to other places in the US.. Yippeee

I liked that there was trippers in for 2 different models, just in case you ordered the wrong one!

Move Along, Not Much To See Here

There isn't a lot to say about the product. Stop pins for an Intermatic timer switch. They work. End of story. I want to talk about how pleased I was to find these close-at-hand, after waiting months for a competitor to produce the WRONG PART. Thank them won't you, for sending me your way?

I liked being able to will-call. I know you are all about drop-shipping, but it is ludicrous to "ship" something less than 5 miles

Great Customer Service

Tuesday, November 15, 2011

I had needed these items for the lighting timers for my business. I had looked through various retail outlets trying to locate them to no avail nor could I get assistance from anyone as to where they could be purchased. I found Drillspot via the internet, placed my order and within a matter of a few days had my merchandise. They were exactly what I needed. Thanks for the great customer service!
