Rated 5 out of 5 by Michael J from The Tester is great! The Website is not! The product is good but the website not so much I have a review of this product on the home Depot website if anyone wants to take a look and ask any questions the rest of this one is me complaining about southwires website I had typed a long review and tried adding some photos and it wouldn't let me add them okay so no big deal so I try going back to my review to submit it without the photos well it was all gone no review no ratings no name nothing was there the tester is great the review section of this website is not very radical to say the least
