Celltreat syringe filters?

[CApump]

Has anyone used these before or have any input on them? They cost 5x less than Whatmans...I am skeptical.

About 2 years ago I went to a distribution channel they have locally and got a trial bottle top filter. Worked great until the base cracked. It seemed very legit to me other than the cracking.
