I ordered the Dual Dock 2 Additional Battery Charger for Xbox One Controllers (I have 2 Elite Controllers) to replace the individual (single controller) Power A chargers that I have had for many years. Packaged arrived as promised the next day. The base holds 2 battery packs and then two controllers can charge on the top cradles. The design is well thought out and the entire unit is compact and unobtrusive. The LED indicators on the front of the charging base are a great feature and are clearly labeled so you can quickly determine the status of each of the 4 battery packs charging. Included in the packaging were several reminders to register the product with Fosmon and contact information for customer service should you have any issues. Unfortunately, I noticed right away that the rear controller cradle was not charging (no LED indication at all, as if the controller was not on the cradle). A quick inspection determined that the charging pins for the rear cradle were missing entirely. After one email to Fosmon Support, a replacement cradle was on the way! They apologized for the issue and explained that, although rare, manufacturing and quality issues can occur. It is obvious that customer service and "brand integrity" are equally important to Fosmon. I think the charger looks and works great and the company is committed to making sure you are happy with the product. I highly recommend this charger and will definitely consider Fosmon's other products in the future.
