Summary:

It is all smoke and mirrors! As you engrave, debris such as smoke and dust land on your focal lens, building up a layer of residue over time that absorbs laser beam power and can stain the lens permanently. Eventually, this lost power will affect your machine’s precision and throw off your laser settings. To keep your device running at its full potential, we recommend inspecting and cleaning the optics system once a week and replacing the mirrors or focal lens as soon they get damaged.

Color: Remote blue
The duraspin dog ball bounces, moves, and vibrates automatically. My Labrador chased it all afternoon and never got tired of it.

Great interactive ball !!
Color: Red
I have an 11 month old golden doodle and she loves this ball! It keeps her attention for a good amount of time I have been using it for times where i absolutely need her to be occupied and so far so good! I was worried she would chew it up but that hadn’t been an issue it seems to be very durable! And so for I have charged it up one time and she has had a few plays with it i should probably go ahead and charge it but lasted good amount! Def would recommend also loovveee that it doesn’t play music constantly ! One main things i was looking for have a few moving ones that are so fern loud I rather her not be occupied 🤣
