The Gulaki Neck Fan is a simple but effective cooling device that sits comfortably around your neck, directing gentle wafts of wind up toward your head. With three speed settings and a ring of 72 air slots for the fan to exhaust through, it can cover everything above your neck without blowing directly into your face (which would be annoying).

Plus, you can hold down the power button and turn each end of the neck fan into a fun color-changing LED light show. Who wouldn&#;t want that?

It has one of the best fan-speed ranges we&#;ve seen. With three power settings, the Gulaki fan can go from a subtle breeze at 1.3 mph to a powerful gust at nearly twice that speed. It&#;s one of the most powerful fans we&#;ve tested, tied with our upgrade pick, the Torras Coolify 2S. By contrast, the fan on our also-great pick, the Egopp 1S Cool Down, maxed out at 1.3 mph.

It&#;s also especially easy to use. The Gulaki fan has only one large button, on the front right side to cycle through the fan speeds. The button is recessed just enough that most people should be able to find it by feel without having to remove the neck fan and look for the spot to press. Most of the other models we evaluated had small rectangular buttons, often hidden on the underside or back of the fan, that were difficult to locate and activate without our taking the fan off to look for them.

The fan&#;s streamlined style is both subtle and comfortable. It has a discreet design that doesn&#;t attract much more attention than if you were wearing a pair of over-the-ear headphones around your neck; in fact, several people mistook the Gulaki fan for a pair of Beats headphones when they saw it.

It weighs only about a half a pound. You&#;ll barely even notice it while wearing it, and its 8.5-inch diameter should allow it to comfortably fit around most necks without sticking to sweaty skin. It&#;s available in a variety of colors as well.

The rechargeable battery should have just enough juice to get you through the day. Like most of the fans we tested, the Gulaki fan comes with a 4,000 mAh lithium-ion battery that can last up to 16 hours or so, depending on the fan-speed setting. It&#;s a particularly good companion for a full workday, especially if you work outdoors.

It usually costs around $30, about the same as other, similar neck fans. Plenty of other brands sell nearly identical (or maybe even entirely identical) devices for around the same price&#;including the Penkou Portable Neck Fan, which we previously recommended as our top pick. Like those other models, the Gulaki fan doesn&#;t come with a warranty. But if it&#;s any consolation, our test unit was durable enough to survive several drops off a moving bicycle and onto the pavement. (Oops.)

Did we mention that it also has color-changing LEDs? Hold down the power button on the Gulaki fan, and the circle at each headphone-style rounded end illuminates in a fun, ever-shifting LED light display. Yes, it&#;s sort of silly. But so is wearing a fan around your neck. You may as well go all the way and have some fun with it. Unless you hate fun, in which case, you can just not turn the lights on. (Our previous top pick, the Penkou fan, looks and performs identically to the Gulaki model, minus the LED option. It doesn&#;t save you any money, though.)

Neck fans in general can sound sort of annoying, but the Gulaki fan is the quietest model we found. In our tests, we measured the volume of the Gulaki fan at 46 decibels on the lowest setting and up to about 56 decibels on high&#;quieter than any other fan we tested, and comfortably below &#;normal&#; conversation levels. The noise isn&#;t particularly bothersome, either, even though the fan is essentially blowing straight at your ears. If you wear headphones with it on, as I did while walking or working, it&#;s basically unnoticeable.

That said, the volume of the fan at higher speeds can interfere with conversations a bit. I already have some auditory-processing problems to begin with, so sometimes it would take me a moment to realize that the problem was the fan, not just me. Keep it running on low, however, and you should be fine.

It is still a relatively low-cost neck fan. We hope that anyone shopping at the low end of the neck fan market is not bringing a discerning eye for high-quality craftsmanship. You&#;ll find no impressive feats of design or engineering here to celebrate. The Gulaki fan has tested well for us and outperformed other models in its price range. We&#;ve seen an uptick in quality since these devices debuted, but their longevity in general remains a question mark, and at this price, there&#;s a chance that the Gulaki fan&#;s components won&#;t last.

Physiotherapists use a variety of devices in their practice such as electric stimulators, cryotherapy units, laser therapy units and pressure therapy units. The following is a list of commonly used equipment:

• Electric stimulators:electrotherapy devices send several types of electrical current (of varying frequency and amplitude) to the human body. They are commonly used for the treatment of pain and for sports conditioning and recovery

  (improvement of healthy muscle performance and rehabilitation of disturbed muscle functions

  ), but also in urogynecology for treatment of incontinence and certain prolapses.

• Ultrasound stimulators: ultrasound stimulators, also called ultrasound diathermy units, send ultrasound waves to treat pain and degenerative inflammatory processes in the joints or tendons.

• Heat therapy units and cryotherapy units: heat therapy equipment uses hot and cold to act on pain, inflammation, edema, skin lesions and muscle tears. Cryotherapy machines on the other hand exclusively use cold treatment.

• Tecar therapy units:tecar therapy consists of transmitting a high frequency current (oscillating between frequencies of 300 KHz to 1 MHz) and combining a capacitive and resistive mode. It can treat inflammation and edema by encouraging cellular regeneration and cicatrization. It is also used to treat joint pain.

• Physical therapy lasers: physiotherapy lasers emit at specific wavelengths and strengths. They are used in cases of arthritic pathologies and sports trauma. There are low-level laser therapy devices (LLLT devices) and high power laser therapy devices (HPLT devices).

• Magnetic therapy units:magnetic therapy units generate a flow of magnetic waves that regulate biological functions by penetrating the tissue. Recent models of these units often work with pulsed electromagnetic fields.

• Pressure therapy units:pressure therapy units activate blood and lymphatic circulation by means of air-filled cells that inflate and deflate, thus exerting pressure on the targeted limbs. They can be used for lymphatic drainage, cellulite reduction, varicose vein prevention, water retention and muscle recovery.

• Extracorporeal shock wave therapy (ESWT) units: shock wave therapy generators deliver radial shock waves that stimulate metabolic activity and increase blood flow. They are used in the treatment of tendinopathies, calcifications, osteoarthritis of the knee and pain in the shoulder, tibia, Achilles tendon and heel.

Physiotherapy equipment can combine several of the devices listed above.
