I like the product except that it’s a bit heavy (hard to hold with just your lips if you are driving for instance). Customer service on the other hand is nonexistent. The fist shift I ordered took two weeks to arrive, so when I ordered the second one as a gift I made sure to select expedited shipping. When I inquired about canceling the order (since a week went by with no shipping notice)…radio silence. No response from Komuso. I emailed again asking if it had been canceled or shipped with no response. The next day I got a shipping notice (13 after order). When I emailed that I’d like to return the item when it did arrive because it was too late, again no response. TLDR; nice item, a bit too heavy, don’t expect any kind of customer service at all from this company or for it to arrive any time soon even with expedited shipping.
