I use this for Fight Camp workouts and it is great. It was easy to fill, just make sure to use dry sand and not wet playsand. The Velcro straps were a bit of a challenge to secure down over the lip but after a few minutes it was all set. And even with 250 lbs. it is rather easy to move around if you need to by tilting it as per the instruction manual.
My first bag, the WaveMaster, was stolen by burglars from my family's Federal Homestead.The Torrent T2 Pro requires more assembly. But, the T2 has the convenience of never needing height adjustment, which the WaveMaster does require.
