Works well, but it's not confident in its own ability

Works well, but if there are only like 4 sheets of paper at once it won't auto feed because it senses it's too thick. So then you have to press and hold the manual feed to get the job done (which it does easily). That drives me nuts. Otherwise, it works very well.

Works as advertised... though it does take some practice to get it right.

Surprisingly for the cost, it does its job.

When it works, it works very well. But it tends to like to fall over and die every 16 or so hours. It does manage to start itself back up, but it's not the best of user experiences when you have to constantly wait for the connection to recover.

not very stable...  loose between clicks, but it does the job.

I had higher expectations with this unit. Overall I am pleased with it, but I wish it was more reliable in its function. I could say more but not needed for this posting

I worry about it's longevity. But it's a pretty solid device. We use it often, and it works.

It works when it wants to, but it could be my controller so on account of me not really knowing. 4 stars

This product works, but, it is not something that is going to last, and that you have to be very careful when using it...

It works but I was disappointed by the fragility of this product.

It does what it's advertised to do, but not as efficiently by itself, as proposed by some other reviewers. The pump is definitely needed to do the job right.

This product works...when it wants to. It seems the device has "sometimes" has difficulty recognizing the input signal and thus won't distribute the signal to 1 or both of its outputs. Its a rare occurance but very frustrating because I normally test/troubleshoot the input and output devices first and then check the splitter...the splitter is always the culprit sadly and I've since bought a different splitter on Amazon.

Not sure why it works as well as it does but it does.

I find I don't use it as much as I thought I would but it works
as advertised when I do.

pretty strong but doesn't function like I thought it would

Brilliant idea.  But it's a bit temperamental.  When I have it working correctly, it's excellent.

There have been three times where I've left this thing in the garage overnight and each time it's ended up with three of the LEDs "stuck on". Leave it in the house for a half a day or so and it'll start working correctly again. My assumption is that it's either the cold temperature or the high humidity in the garage that's causing one of the sensors in it to give false reports. I knocked two stars off for this. I'm curious whether others have noticed the same thing or if I have a bum unit. Unfortunately, it's not really "user serviceable" so I cannot get inside of it to diagnose the problem.

When it's working, the tool is great. The primary advantage is that it doesn't matter where you initially place it on a wall or how fast you sweep with it. A secondary advantage is that it seems to accurately show where multiple studs are located. It's also better at showing stud boundaries than my previous stud finder. I don't feel I need to pound a bunch of nails into the wall to see if the reading is accurate -- I can trust it. That's a huge timesaver.

The only place I've found it was unreliable is one spot in my garage where someone put drywall over OSB sheeting. It sometimes found studs, sometimes didn't. I'm surprised it worked at all in this case.
