Tria Plus 4X Laser Hair Removal Device

This is the Tria home hair removal device haha. Actually, I think it's been almost 10 years since I bought this product.
I paid quite a high price for it back then, but I just looked it up and it's still being sold at a similar price.
I understand that smaller, lighter, and quieter products are being released these days.
This product is quite heavy, bulky, and a bit noisy, haha.
Nevertheless, the laser hair removal effect is very good.
Of course, you have to do it consistently on your own, and it stings and is a hassle, so there are various downsides.
If you want 확실한 (definite) results, I think it wouldn't be a bad idea to have a home hair removal device.
