This is I think the 3rd of these coils I’ve bought from discountENails. I have a Crossings PID and an Auber PID. This site is the only one that sells a 100% compatible Crossings brand enail coil. These coils have the standard XLR pinout that is the most commonly used pinout assignment by PID temp controllers. These coils are very high quality, I have never had a single one go bad on me, they work with every PID that isn’t HighFive brand, this site sells them for under $35 when they next cheapest 20mm barrel coil or other is around $48 plus over $11 for shipping totaling over $60 vs $34.99. DiscountEnails processes orders almost immediately and your order is efficiently shipped out to you with tracking and always arrives a day or two early. Whenever I have ANY NEED for ANYTHING that DiscountEnails might sell, they are definitely the FIRST place I check. Great online retailer all around in an industry full of bad ones. I highly recommend these coils for their versatility and longevity as well as a very low price.
