Magnets could be stronger

Everything attached to the scope perfectly. While the magnets hold my filters in the drawer, the magnets seem a bit weak. Stronger magnets would easy my mind a bit about losing a filter holder in the dark.

A little bit too convenient.

I have had this less than one day and I have one broken L-Extreme filter to show for it. You do need to secure the drawer in some fashion other than the magnets which are too weak. As other reviews have mentioned. I will try a rubber band as I cannot easily get to the lock screw. I'll try to salvage the filter, but so far a rather negative experience sorry to say.

Convenience and speed when changing filters

I purchased this filter drawer to use with my ASI533mc Pro. It fit into my image train and enabled me to maintain the 55mm backspace based on the diagrams on the ZWO site. It makes changing filters very easy and does not require breaking down my image train to swap out a filter. I ordered an extra drawer so I can quickly swap out filters when needed. For example if I switch targets from star cluster to nebula and want to change the filter I am using on the target.
