This is the second ART power supply I’ve bought. The first is in another rack. I gig quite frequently and these units provide all the filtered power I need for my digital keyboards and computer. Having the light in back of the rack is a god send in dark venues and the usb ports come in handy more than I thought they would. I highly recommend this.

I bought this item a year ago and I am still completely satisfied that I bought a second as I upgrade my set up. You can't beat the flexibility and features for this price. I would recommend.

I must say as someone being in the sound industry for 12 years and my father for over 30 + we have had many types of power stations this it not only the best but is by far more than reliable for many years we have the original models still pumping our very sensitive and important equipment safely qe have had many power problems and with everything that we have had to fix anything after the unit and the unit it self has been working and never had seen it effect anything it saved us many times please if you want to keep equipment in good condition buy this it will never let you down

I'm surprised that I am taking the time to write this but I feel that it is my responsibility to share the love on this product. It seems that the lowly, mostly forgotten about power conditioner, is the most vital part of your rig. it can ruin all of your other gear if you go too cheap and likewise it can make your setup go more smoothly with the right match of components. Like most if not all of the ART products I own, this conditioner strikes the perfect balance of cost, features, and durability.Big improvements over previous power conditioners:LED lights upfront. Gooseneck light in back, USB outlets, and a digital meter for the current draw! these features all have me considering buy 3 or 4 more for my studio and live rig.

I purchased this unit for use in a communications rack I use for portable amateur radio operations. I do this in a great deal of RV parts with have the noisiest switching power supplies known to man. This unit helps to filter all that noise from the radio power feed. The lighting options, front outlet and USB outlets are a nice feature also.

This product is well done. I'm very pleased with the features & looks great in my studio. I had to get this because of a recent lightning strike. I should've gotten this a long time ago. You live & learn.
