Still sourcing mine through Tomtop, eBay Tomtop auction on the last batch. Been buying them from Tomtop for year and a half and product has stayed the same over that time. Flush switch, OP reflector, correct clip. Tint has varied a little batch to batch but they’ve been reliable and I’ve gotten good reports from giftees. Probably gifted 50 of these things, keep going back to Tomtop.

Some of their listings ship from California. That was the case with this one, took about a week to Midwest US.
