Yes, it seems solid, and it’s definitely affordable. I do prefer Zebralight headlamps as well (smaller and lighter), but they are 3 times the price. So, the HL01 falls into the budget value category. The HL01 also comes with more features and bling. My wife has already stolen it to work on puzzles at night, so we don’t need a bright light on in the room. So, it’s definitely going to get used.
One thing the HL01 has, that I sometimes wish my Zebralights had, is a magnetic tailcap. Those are really useful in some situations. Though, I admit I probably won’t use the magnet a lot. And, of course, it adds to the size and weight.
