I just received this a couple days ago. I had just a regular $40 neck fan and didn’t have many complaints for what it was—only had three modes but I work in door to door sales in hot and humid northeast PA so I appreciate any relief. Luckily found this one on sale when the charging port broke on the old one, and I can definitively say my expectations have been exceeded by this fan. The quality is exceptional. What you see is what you get. Has a very nice, compact hard case. Very high quality USB-C cord. There are six slots for the fans, and the plates are large. I have not run it long term with the plates on. The most I had it was for about 6 hours with the fan on low, and about an hour on the second cooling setting. You can just run the fans, the cooling plates, or both. There’s 3 fan speeds, 3 cooling settings, and 3 heating settings. Just to clarify the fans are not a part of the heating function. I will follow up after a few months, but absolutely worth the money; quality and function are great, and it conforms perfectly to your neck. 100% recommend.
