I haven't done it yet. Smartrise supposedly has a full mod package for Ecospaces, with a five year warranty on everything electrical. They keep the Kone machine I believe. Replace controller, operator and all fixtures, selector etc.

While a huge improvement over the OEM equipment in my opinion, it still leaves the customer with a machine and car/cw sheaves that are non greasable and will cost them a ton when bearings start to go bad. Everything about them is not good for the customer. Good for architects and the big 4's salespeople.

If it's low rise it may be another good option to discuss removing the whole thing and sticking a hydro in there.
