Would you use harbor frieght wagos

Harbor frieght is selling these lever nut packs for a very reasonable price. Would you use these in a pinch, use them regularly or avoid at all costs? They are UL listed, costs for one of these small packs comes to be slightly cheaper than even the large bags/boxes of wagos per unit, but they are not as compact. Personally, I'm considering trying them out when I rewire my barn but wouldn't even bring them up at work
