First impression after installation is very good. The quality looks really good for the price. Used this to replace a Vixen pump which was just a problem. This one is much quieter, better built and pumps much faster. Will be updated after about a week of use. Update: It's been 4 weeks since installation and I haven't had any problems. Tests have shown that it fills about 3 times faster than Vixen and only takes about 2 minutes to adjust the pressure in my 7 gallon tank from 115psi to 140psi. Very impressed and would recommend.
