Welcome
I have a 6 inch with a dream mat.
I find it works really well as long as you have a nice steady flow of water (same as all of them).
Really sturdy build and easy to clean with only 2 bolts.
I am a fan.
Cheers
Had a great day, went though to Whroo. Spent about 8 hours and me knees feel it today. Lots of lead shot, bullets and wire. Plenty of hot rocks as well. Will definitely go back it is a massive area.
