It is great to have ability to look at some additional settings explanation when you are away.
Even then you don't use it too often, having assurance that you carry this book is worth the purchase.

A bit pricey but, it does work well.  It's kinda fun to go around and measure all kinds of distances. I use it in my line of work.

This is such a nifty gadget.  While the odds of needing to use it seem exceedingly low, it would nonetheless have to be easily accessible if you ever did need it.  Having it on the keychain right in front of you is a good idea. The clip that holds it to the keychain is sturdy and requires a deliberate amount of effort to release.

They make great gifts and people seem glad to have it.

I have purchased two units in the same model. Unlike many other carbon monoxide detectors of its kind, I really like how this particular model auto records the last reading, plus other visible features, such other indicators. I gave this item a 4/5 stars because it is quite pricey ($25-26 plus tax; supersaver itm so no s+h) and lifespan is only 7-years. Noteworthy is unit is backed by a 5-year warranty. Overall, I like this item for its compact and functionality.

I have been messing around with it for two days now scanning everything from my tattoos, hands, my dog and just about any thing you can think of and picks everything up no matter that the surface is (so far)  for those like me that can't afford a full size scanner  this is without a doubt this is something that can go with you and copy documents that you might have to sign or copy receipts. in a day and age where everyone wants proof of something this is well spent money

Use it all the time to see if my thermostat is accurate and to tell when I need to plug in the humidifier. Super handy little thing.

I love it. It's a little pricey and I wish it slipped on and off my belt a bit easier but the keys come off just as conveniently as they go on and that is everything for me. I haven't found another key holder that does that.

Cooler is extremely handy. I felt like it was a little overpriced but there's not much else to compare it to. Originally we had issues with it tipping over but when I was writing my review I noticed the photo and discovered the base extends out further, making it much sturdier.

This is a really good quality swab but it is a little on the pricey side. That's ok because it does the job really well and it is worth it.

I'm giving this five stars because it really came in handy when I needed it.  Frankly, if you don't have this already then you should get one.  I attach this to my keychain.  Now that I know that I have it, it's so useful!  It's casts such a bright light for such a little thing!

Here are a few examples where this baby came in handy.  Ok, you're probably thinking - I lose a lot of stuff.  Now I don't since I have this little flashlight!

1) Great for when your porch light is out (or it's super dark outside) and you can't find your key hole
2) Great for finding where you dropped your sunglasses in a dark movie theatre
3) Great for finding your lost earring (any jewelry) in a dark parking lot.
4) Great for checking your oil and finding where the oil thingamajig is located.
5) Great for finding lost items that you've dropped in your car, underneath your sofa, underneath the bed, underneath furniture...you get the drift..

I would buy this for your key chain.  Trust me, you'll thank me for it.

This is the most handy device in my treasury of tools. It will allow inspection of items other than watch repair. I really like it.

Thought it was a bit pricey for just a hunk of metal, until I saw what the other websites were charging for it. Use it for checking overheated cylinder heads, saves me a trip to the machine shop when they're not warped.

It's all kind of Handy for getting something that I would never have thought to bring it along until I saw it for sale.
