it's useless and actually WRONG

the bracket is SOLID, no problems there. But the installation instructions mention nothing as to how to install the rivet nuts, which made me spend an extra 3 hours, cuz I had to go to homedepot to find some kind of tool I could use to install the rivet nuts. Also, the drill hole size that they ask you for, 5/16, is NOT in any regular drill bit kit. You must buy one of those cone drill bits that can drill out bigger sizes, and that will have the correct size for the hole they ask you to make on the instructions. The way they explain to install with a washer and nut, it's useless and actually WRONG. You cannot install the rivet nuts that way, they will never crimp inside the holes. After i figured out what to use to install them, everything is working very well. like I said, the brackets are strong, and after several off road rides, I haven't noticed any loosining of the bolts. Also, you will need to use locking washer for the actual light bar bolt, otherwise the light bar weight will make it spin downwards and you will have to reset it back to the original position aften. Use a large allen key so you can tighten it really well and use the locking washer between the light bar and the bracket, and the light bar should stay in place even on the roughest of trails. Cheers.

This product is useless.

This thing does not work at all. If you buy this, you are throwing your money

In my opinion this is poorly made and not functional.

There is no capability to help a baby walk. It is totally useless in that respect.

1) Both scales are inaccurate -- off by ~1/32 over 6", ~0.5mm over 15cm.

2) Unfortunately, the scales' inaccuracy isn't uniform and therefore the centers aren't actually centered.

3) The edges aren't straight, and so they can't even be used to draw a straight line.

Overall, two useless pieces of metal.

Has proven to be totally useless. Money wasted.

I really have no idea if it is functional.

A friend of mine has this book and it is already wrong a few chapters in. I've not read much, but from this one example I can gather that this was poorly written and god help anyone whose professor requires this book.

The book states clearly, "The actual disk's capacity sometimes is different from the advertised capacity because of bad sectors on the disk."

This is oh so very false.

1K bytes = 1024 Bytes, and 1MB = 1024 KBytes, and that is how it's been from the beginning. However, Hard Drive Manufacturers simply use 1K = 1000, 1M = 1000000, creating about 7% difference between advertised and actual format size.
The system Hard Drive Manufacturers actually use is called binary prefix, as seen here: [...]
as compared to what we are all used to, decimal prefix
[...]

This is actually quite simple, and for the author of this book to say it is because "something partially breaks and kinda messes it up" is wrong. You have to TRY to get something that wrong.

Don't get this book.

Whoever was responsible for designing this should probably be fired, and if they can maintain any sense of personal decency, they'll seek work in another profession. Maybe gardening in a nursery. Maybe herding sheep. Just not anything related to engineering or product design. The corners that were cut in the design of this product don't even make sense. Make no mistakes, this is a bad product, and I can only recommend that you avoid it.

Also, somebody needs to have a word with quality control, because I'm seriously doubting that this was just a one-off mistake. There are problems with every aspect of the gauge that should have been caught and stopped well before someone agreed to sell this as a product. This shouldn't have made it into the hands of a customer.

This didn't come with instructions. It did come with an exploded parts view and that was enough for me to put it together, but it shouldn't have taken as long as it did. A simple page with an accurate breakdown of the steps would have been better than nothing. There isn't a part of this gauge that doesn't shake, wobble, rack, or rattle. The bar, the handle, the gauge, the clamp, the everything. Nothing is quite right.

You can see the grinding tool marks on the handle. Sure, it's cosmetic, but you can actually see that nobody put any effort into actually making this.

This does have a few small upsides though. The handle casting is surprisingly good. The trigger mechanism, though basic, is mechanically functional. The way it's attached to the arm with the clamping screw is shameful, but the basic clamping concept is at least tolerable after a little fine tuning. Thankfully I bought this for a sander. I would be terrified to consider this a table saw accessory and using it would be like begging for kickback.

It is a useless product. I have no ideas what the designer was thinking. It is cumbersome and a waste of money.

This is a decent design concept, but it is completely screwed up in this implementation. The  min and max pointers are intended to tuck under the main pointer when resetting. But in fact they do not fit that way at all. They bump into the main pointer The closest I can get the min and max to reset position is 1 and 2 degrees C respectively. So right off, the total error is 3 degrees C. Furthermore, the F scale is tiny and is mainly hidden behind the three pointers. This is a totally useless device at a ludicrous price. Skip it.

This product is a waste of money, you might as well not even use it. Completely misleading and a waste of money.
How is this allowed to be marketed when it does not work as advertised?

I bought this device for use in Wireless Smoking as well as to check mash and water temperatures for Homebrewing. Quite simply, the accuracy of either probe is not close to the actual temperature at all. Each probe is accurate to about + or - 5 degrees of the actual temperature, and they also fluctuate when reading from a known source such as boiling water. For example, if you take a reading of boiling water one probe might read 214F, while the other will read 209F. For smoking meats and brewing beer, this makes the device all but useless. I've only used it a handful of times, 3-4 times total and the temperatures are already completely inaccurate. What a waste of $70, and with a 90 day warranty this thing is a joke.

Even if it was accurate, the interface is the messiest and most poorly designed I've ever seen on any type of temperature probe. It's as if it was designed by gerbils, and syncing the devices is a lot more finnicky than it should be (Lots of rebooting each for no reason, they don't just magically sync like they should... every once in a while they will though). Choosing a meat and a set temperature couldn't be more difficult, and I have to consult the manual every single time to navigate the myriad of inefficient and confusing menus, because there's no way you could ever figure it out on your own due to the lack of any sort of logic being used at all whatsoever in it's implementation.

Because of it's inaccuracy, you could ruin a batch of beer hitting the wrong target temps, or while smoking meats you could risk poisoning your family when one of the probes reads 140F when it's really 135F, or also end up overcooking your meat when it's reading high. Stay away from this shoddily designed product at all costs!

I'm willing to bet a lot of the positive reviews never actually took the time to compare the readings of both probes, which never match up, nor did they test their accuracy in boiling or ice cold freezing water. People are unfortunately busy or lazy and don't tend to do these things, but it's essential if you want to make sure it actually works.

This does NOT help see any better, but it is actually in the way. Cant place it at eye level (unless you are over 7 ft tall) Definitely a useless piece of junk. If I could've given it no stars, I would have. DO NOT BUY IT!!

I hate it when people say "Do you believe this.  You're wrong." Yeah, that was every other paragraph.  No room for the differences that make this country unique.  Everything in this book basically says if you don't think the way he does, then you are WRONG no questions asked.  Don't waste your money unless you are uncabable of thinking for yourself.

After having tried to use this for a day, I realize that it was 30$ wasted. Even though 30$ lost is not the end of the world, I just really hate electrical stuff that does not work. How hard can it be to make something which works as it should?
I have never used any printer as bad as this, nothing works, the error messages are non-understandable, and the instructions manual is horrible.
Please, if you are looking for wasting money, buy something more useful instead, for example an electrical potato cleaner, I guess it's ten times as useful as this product.

This books is terrible. It is highly inaccurate and misleading. I bought it thinking it would be good for my students and immeidately rejected it for them.
