LED Bicycle Rear Light Waterproof MTB Bike Taillights 3 Lighting Modes Aluminum Alloy Bike Light for Helmet Seatpost

Really bad! I bought two units, and neither one works. I thought the batteries were dead, so I went out and bought another set for 100 baht—two CR2032 batteries. But when I tried to insert them, the spring-loaded pin broke on one unit, and the pin on the other unit snapped too. I even pressed down hard until the original batteries got dented. The design is just awful! There’s no manual either. I’d like a refund or at least a replacement. I’m really frustrated! Even if each one cost 500 baht, that wouldn’t bother me—if only they were durable and actually worked!
