They work as they should.

Thought I was going to have replace band, which is perfect, they send you 4 of them, which will last forever.

Le falta un milímetro de ancho queda algo ajustado

Fits my T-rex band like a charm. The band broke fairly early on, so I'm glad to have a package of spares to go along with it.

Beats buying a new watch. Better than what came with the watch. Easy to install.

The information on the website was extremely accurate and it was just what I needed for my replacement watch band. I couldn't be more satisfied!

These are advertised to fit the T-Rex 2 band. I have this watch currently, and one of the 2 rings broke, so I thought I'd give these a try. They BARELY squeeze onto the band, with absolutely no give when trying to insert the loose end of the watch band. There are these handy notches on the other side of the rings to keep them in place in one of the watch band slots, but because of how tight they are, adjusting them to the correct slot is impossible when the other tag end of the strap is inserted. Oh well, you get what you pay for. I'd say save your change and buy and actual replacement band.

Love my T-Rex Pro, but original ring wore out. These replacements work perfectly.
