This Vividye UV resin glue is good! It sticks well and is thin enough to get into cracks easily.
I had a cracked acrylic ball. I filled the cracks with this, UV blasted it, and the repair is holding.
It took quite a while to get 20 seconds on every bit of the cracks, as the included flashlight has a very small spot. I think it's made for curing small spot repairs.
As a bonus, I don't have to swipe my daughter's UV nail glue now to fix things 😊
One point is lost for the charging cable. USB-C was mainstream in 2015.
I got rid of all my micro-USB and older stuff about 5 years ago. I got tired of all the cords.
There is NO reason to still have a vintage MicroUSB charge port on something new in 2025. It's just annoying.
