(Amazon) replaced it free of charge and sent a return label for the failed unit.

This compact little unit fit perfectly in the available space

The unit has worked perfectly in keeping 2 boat batteries in peak condition.

Originally I wanted a portable unit that I could clip and unclip from the boat batteries as needed (which would not be very often as the engines usually provide sufficient charge), but a permanent charger seemed much simpler

As a side note, if you haven't picked up on this yourself, someone returned a defective unit that was obviously never even re-inspected because it had a random set of instructions.

Nice compact unit

Outstanding unit!!!

my unit dead just after the 2 year mark and NOCO wanted me to send it back to them and send them a check for 58 dollars .

I put a hand written note in the box stating the unit is defective & to return immediately.

This unit was not cheap, but in the long run, it will save me lot of money by NOT cooking my batteries!

The third unit just failed.

Some of those overpriced units just have one charger that is multi-tasking to charge 3 batteries (and straining to do it)I highly recommend it and this company.

Can't really speak to the performance of the charger as we haven't received a non-defective unit.

All things considered, the pros heavily outweigh the cons and I strongly recommend this unit for a garage, storage shed or boat house.

I tried the unit on several auto batteries and a riding mower battery and it worked as stated in their brochure.

If you continually hooked it up and unhooked it without clamps you would eventually damage the unit

It is fast and a very solid unit.

Good quality unit

Great unit for a great price

They absolutely refused to replaced the defective unit I received!

Love this unit

This new unit was easy to install and hook up, and charged two batteries after a winter of sitting idle in NO TIME!!!

She finally said I must have a bad unit and that they would send me a replacement

don't confuse this unit and it just picks up where it was before the power was interrupted

Seems to be a good unit, keeps my batteries up, takes up very little space, price was very low compared to similar units.

This seems t be an excellent unit.

Hopefully the next unit actually works & I will update my review.***UPDATE***New unit came in, and the box was still in the plastic wrapping which was a good start

A VERY NICE COMPACT UNIT A GREAT BUY

This compact unit does the job well.

besides my life partner this is a great little unit.

The Genius has multistage charging typically found in much more expensive units.

It works, but my unit gets very hot.

nice unit

Oh well, nice unit, no nonsense, just plug it in and go!

I recommend this unit.

Nice unit

It worked very well for the first few months, so it is possible that I simply got a defective unit

Great unit, solidly built and has decent reinforcement where the cords enter the unit

Make sure you have ample clearance, otherwise, the unit is fantastic

This unit is about as good as it gets for what it does.

This is a very good unit

Not a good unit

Worked great for a day, burnt out, they replaced was just a faulty unit

Nice unit!!

I purchased this unit to maintain my boat batteries less than 3 months ago and one charging bank already failed.

I interacted with Noco support and they said the unit was defective and suggested a return.

Amazon makes the exchange of a defective unit as painless as possible sending the replacement before receiving the defective

Unit hasn't been hot anytime that I've walked by and held my hand to it,

I used this to replace a much larger (floor stand Sears Die-Hard) unit that is about 2.5' high

This is an excellent unit, no more dead battery on my RV.

Nice unit though

No need to worry about overcharging, this smart little unit is bullet-proof

The second unit once tested and installed has worked flawlessly and cuts on and off appropriately to keep the batteries in peak

I like the design, the unit feels solid, and it was easy to set up and use.

A nice unit for the price and look forward to years of happy boating experiece.

Excellent unit

I love the feel of this charger, feels like a solid unit, but I can't tell you how it works because mine would not power on

This unit trashed 2 deep cycle batteries by overcharging them

it t keeps my batteries charged and ready for action.
