I purchased the 4 piece Brookstone Modular Winder System and an additional single winder back in 2012. The winders are set to 1 TPD and Bidirectional. Prior to this product, I have purchased many other winders varying from $100 to $600 and they have all failed after a year. This Brookstone watch winder, and my watches, have been with me all over the world for work from Afghanistan to Hawaii and have remained perfectly operational and trouble free until now. One of the 5 modular cubes has failed and no longer rotates. No problem! I just ordered a replacement cube and now Im back to fully operational. This is the most reliable watch winder I have ever owned and I cant find a better product for my automatic watches for less than $1000. I hope Brookstone will continue to manufacture it.
