No interruption to the optical train when moving to different targets and needing a different filter. Great time saver! Got it before the Christmas rush!

Typically easy and efficient service from FLO. Items arrived quickly and were well packaged. The filter drawers are made well and really help reduce set up times.

This makes it quick and easy to swap filters, reducing the risk of cross-threading or dropping them. Not cheap, but still less expensive and less heavy than a manual filter wheel

I think these spare drawers are great for those not using filter wheels. Makes for quick changes, keeps the optical train intact so nothing is disturbed. Especially handy are the plastic cases they come in so you could keep your unused filters mounted and safely stored in these hard cases.
