I just bought four pair of some nifty Celestron 8x21s for an incredible $12 each! They are compact and very light weight. The eye relief is great, and while they ain’t Swarovskis, they do the job just fine. And best of all, I don’t worry about losing them or getting them scratched. My advice is to buy a bunch and keep them in every car, backpack, etc.
I did just what Paul Saffo suggested. I got me a couple of these. They are small mini-binocs about 6 inches square — the size of your palm. They are as sharp as my other mid-price pairs, but much handier. I really like them. And for $12 (the current price is $18), they are unbeatable.
This is a Cool Tools Favorite from 2003

A couple of observations. First, the links above both lead to the same model but they both look much different from the picture above. Second, the price is now $17.90 (You Save $-2.95) at the links given. Love that negative savings. ;-) Try getting them directly from Celestron for $12.95:

These are some of the nicest mini-binoculars I’ve used. The price is right – currently $16.99 from Celestron. They are very light weight, extremely compact, with decent optics. I recommend them for the trail since they are so light.

KK: the link isn’t working. I went to the site and could only find the Celestron “Up Close” 8×21 for a similar price……. http://www.sh0rten.com/1wg0puaopft/

I bought three pair of these based on these reviews. The binoculars are fine, but I wouldn’t recommend getting them from Celestron. They use Shopatron for fulfillment; my binoculars took nearly three weeks to reach me. Celestron isn’t at all helpful; once the order is placed you see a notice saying that the order cannot be changed or canceled. Two weeks later I was unable to find anyone who was willing to take responsibility for finding out what was going on with my order (“we don’t have anything to do with fulfillment”), and it was nearly another week before it finally showed up. — editors)

Open or close garage door without a key or remote
If you have a motorized garage door opener, you may know the frustration of not being able to get in because you don’t have the remote handy. The keyless entry solves this problem by permanently mounting a remote with PIN pad near the entry. There are a wide range of models to match different systems but they all do basically the same thing. After you screw it to the door frame, you sync to the opener and program in a code. We find this incredibly convenient and it also makes it easy for the kids to take their bikes in and out to school.03/22/18

Low-cost, keychain-friendly multitool
I’m a scientist, I don’t need to carry an EDC knife with a tactical blade and one handed spring assist opening. But a handy little (closed length: 2.25″) keychain knife with screwdrivers on it is a great tool to have. I have had my Gerber Curve multitool ($10) on my keychain for years. It has everything you need, a small blade, phillips and straight screwdrivers and a file. I have actually added one to my bike bag and my photo bag as it is just that handy.03/21/18

$11 for 1000 feet of non-adhesive plastic film
Let’s talk about stretch wrap. $11 on Amazon got me 1,000 feet of this stuff — but what’s it good for? I’ll tell you what I use it for, and if you want to pick some up for yourself, using the link in the description helps support my videos and the Cool Tools blog.
Stretch wrap is a non-adhesive plastic film that under tension will stick to itself. It comes in all different sizes. This roll is 5-inches wide and clear and comes with this built in cardboard handle.
What’s great about it in general is that it’s non-destructive — you can use it like tape to wrap things up, but it won’t leave behind any residue or pull anything up when you take it off.
You’ll often see moving companies use this to bundle up loose things that won’t fit in boxes, or secure furniture or drawers so things stay together.
I stole this tip from Jimmy Diresta’s video on tape tips, he uses stretch wrap for securing ratchet straps in his truck into a nice bundle. He also recommends it as a way to secure things in bubble wrap without resorting to packing tape. This way, if you mark where to pull to unwrap it, people can undo the packaging without having to slice into it and possibly damage the contents.
I picked this up specifically to organize the t-shirts my band sells at shows. I’ll fold big stacks of shirts grouped by size and wrap them with this so I can still see the size on the tag. I used to use rubber bands but they would leave marks or wrinkle the fabric — but this doesn’t.
On that same note, I have things in my workshop like grillecloth or corkboard, that tape or rubber bands tend to damage. Stretch wrap is a great way to safely bundle it up.03/20/18

Fan recharges with USB cable
If you’ve ever battled over the thermostat setting, this fan will settle a lot of arguments. I have been using one of these small battery-operated fans for over a year, now, and it’s still going strong.
I experience hot spells several times a day, and this fan provides instant relief. It can be operated on batteries or with the included mini-USB cable, but it lasts long enough on one charge that I’ve rarely used it with the USB cable. Initially, the fan would last for over two weeks of daily use (several times a day, for five or more minutes at a time) on one charge. Even after over a year of daily use the 2000 mAh battery is still going strong, but now lasts for about a week of regular use on one charge.
The fan has three speed settings, but I generally use it on the middle setting. It’s reasonably quiet, for how much air it pushes. It folds up for storage, and it even has little hooks that can be used to attach it to the underside of an umbrella, though I’ve never used it that way. There are models available that come with rounded handles, but I find the flat-sided handle useful for propping the partly folded fan on a table so I can direct the cool breeze in my direction.
Amazon no longer lists the exact brand of fan that I initially purchased (iEGrow), but there are a number different models available, all in the $12 to $15 price range. I expect that they all perform about the same, and I recently purchased another model that came with an extra battery (for a few dollars more) so I can store enough juice to run the fan for several weeks of daily use without needing to recharge batteries.
One thing that is a bit odd, but not a problem for me, is that when the battery is very low, the fan does not turn off, but instead cycles between low and high setting when you press the switch. Charging probably takes several hours, I usually just charge it up overnight, and I’m good to go for another week or two. It is a bit difficult to see the indicator light to know when it’s fully charged, as the light is recessed inside the handle. I have been waiting for my first fan to die before I switch batteries, but although the battery has flagged a bit, it shows no sign of quitting, after being recharged dozens of times over the past fifteen months.
This fan gets so much use that I really don’t know how I got along without it.03/20/18

ABOUT COOL TOOLS
Cool Tools is a web site which recommends the best/cheapest tools available. Tools are defined broadly as anything that can be useful. This includes hand tools, machines, books, software, gadgets, websites, maps, and even ideas. All reviews are positive raves written by real users. We don’t bother with negative reviews because our intent is to only offer the best.
One new tool is posted each weekday. Cool Tools does NOT sell anything. The site provides prices and convenient sources for readers to purchase items.
When Amazon.com is listed as a source (which it often is because of its prices and convenience) Cool Tools receives a fractional fee from Amazon if items are purchased at Amazon on that visit. Cool Tools also earns revenue from Google ads, although we have no foreknowledge nor much control of which ads will appear.
We recently posted a short history of Cool Tools which included current stats as of April 2008. This explains both the genesis of this site, and the tools we use to operate it.
