Any thoughts, comments or experience on them?

I found them unsatisfactory because it was difficult to regulate the moisture
content.

I used them commercially with the same results - waste of money and time.
For most veg seeds I use plug trays. For most ornamentals I sow in small trays or small pots and prick out as needed
into standard trays, plug trays or pots.
