Do you need extra ventilation power for your CO2 laser engraver? 

OMTech's inline duct fan keeps your machine and workshop as fresh as a daisy. Designed for 4"/6" ducts, this ventilation and exhaust fan eliminates odors and keeps your environment habitable thanks to its 2500 rpm rotational speed and 200 cfm airflow. While the sturdy base and aerodynamically designed impeller ensure smooth operation, it works quietly under 50 dB even on high with the help of added PVC cover which further muffles any sound and vibration. The galvanized steel casing, PVC cover, and PA66 blades offer durable service and corrosion-proof performance in laser engraving machine workshops. The external speed controller allows granular control of the fan's speed to meet your needs. Install it in only a few minutes at the height you find most suitable thanks to its intuitive design and clear instructions.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.

My dog loves glowing fetch at night!
Style: Glow Balls (Pack of 3), Size: 2.5 inch
Fantastic. Sturdy. My dog loves them Glow in the dark is great for fetch at night. I keep a flashlight with me because the glow doesn't last really long. But they charge very quickly and are really bright.
