3 if you're good at rolling them tight

I have had this Mini Hot Towel Cabbie for about 3 months now and it does not get as hot as it did the first couple of weeks.
 When I first got the unit, I'd have to take the rolled up damp towel out of the cabinet and shake the heat out of it before putting it on my massage client. Now: 3 months later,
I have to warm it up at least 45 minutes before using the hot towels on my client in order to get a fairly warm. I would call this a warm towel cabinet not a hot towel cabinet. Also, it  barely fits 2 hand towels. 3 if you're good at rolling them tight.

They were a little loose, but the standard size I purchased at Lowe's are so tight, you have to rip them out; these are working out just great.

I never got another flat after getting these. However, I also had armored tires. Prior to the armored tires and heavy duty tube, I got a flat every week. Afterward, I went a year and no flats.

Why only 4 stars? Armored tires and thicker tubes add rolling resistance. The extra resistance was not bad, but I just did not roll and coast as effortlessly and continuously as I did with the standard tires.

If you want to get to work in a predictable amount of time and don't mind a little exercise, get these. If you want to win a race and don't mind having to change a tube once in a while, skip these.

Tighteners are a bit hard to get snug....better if they were wing screws or something.

They get 4 stars because they are not easy to roll once you put items in them. However if you sit/lay on top of them they will release the air and compress. They worked great though to help me bring more items in my one luggage bag for a 10 day cruise.

I have some of these that have a different wasteband that is much softer (covered with material) and more comfortable, these are more like tighty-whities in the wasteband.

These for the most part do what they are supposed to do, keep from bunching up your back-canyon or wadding between the goods and your legs - you gotta keep 'em seperated! I have tree trunks for legs, which these will grab on to and stay in place without issue.

Seriously though, they do the job, they do tend to wear out, but they're cheap and easily replacable. They're not stylish, so you won't want to 'extreme-sag' with them on, which is a good thing as everyone is pretty tired of that and it seems some people just didn't get them memo.

I like them a little hard to get in and out of because you should do it a certain way.

I have both the 3/8" and 1/4". I simply couldn't work without either one. Ok, so they are not made for the professional nor are they priced for the professional. Common sense would tell you to break the fastener loose first and then use these ratchets to turn a ten minute job into a one minute job. The same applies for tightening. Lubrication helps keep the rotation mechanism operating smoothly. Anyone giving these a low rating has probably torqued on them too hard. I give these things away as gifts and my friends love them.

Nice product but balls in roller don't always roll smoothly.

They work fairly well except for them constantly rolling up which is very irritating  didn't realize they would do that

These actually do to secure the polyrope tight enough. Lots of slippage. Better of tying a knot. :/

Works well, no real issues, except that they don't stay as tight as I'd like.

Don't let the name fool ya - tight waistband rolls over easily

These are ok, they are a little too tight for my main squeeze. I'm not sure if he's average or above,but I guess it's not one size fits all. And I made up a fun game called condom roulette, you poke a hole in one of the packages and in a heated love session grab a random condom from the box. The game is more fun if your partner doesn't know about your fun hole poking. We're almost out too!

These work astonishingly well when it comes to learning stationary tricks; however, one difficulty which ought to be made known is that moving to rolling attempts must be done fairly early in the process so as to minimize the negative impacts of becoming too comfortable landing at both akward positions and too far off center.
