Button is hard to press. You can deck more. It is also quite troublesome to hold down for 1 second. Brightness is probably OK !. Vertical direction? Angle adjustment is rough. Even if I want to make a bit upward, I look upwards. I want fine adjustment here. Batteries ranked 1 hour in 1 time, 3 months in 3 days a week.
Currently, I use the old type of CATEYE (TL - LD 130 - R). About 1 year, using about 3000 km, non trouble. (At the same time I bought a similar one at a 100 yen shop, I was in trouble on the go after 6 months.) I was in trouble.) In addition to the current TL - LD 130 - R, purchase it for purchase. Since this product can see light also from the back and side, it seems to be high visibility from the car etc coming from behind. It was useful even in the night driving when 200 km running the other day. It is recommended.
