The market for IPL devices designed for hair has rapidly expanded in recent years, and there are now a large number of options available on Amazon.Having personally tried many of these IPL devices, it's clear that most work pretty much the same, with only minor variations setting them apart. When it comes to hair removal, the most significant discrepancies typically revolve around power (wattage of the AC adapter), ergonomics (device shape and button placement) and the inclusion of "ICE" functionality, which actively cools the targeted area during treatment.This particular incorporates ICE Cooling functionality, and performs reasonably--though it is a bit on the high end, price-wise, comapare to other IPL devices offering similar features.Specifics of this IPL device:** Only performs hair removal** Includes ICE skin cooling functionality** LCD screens show the number of flashes left and power level (1-6)** Rated for 48W (medium power for a home IPL)** Stick shaped** Rated for 999,999 flashesBy utilizing slow-motion photography, I managed to capture a snapshot of the light lasting approximately 1/100th of a second (refer to the attached photos). Keep in mind that the duration of the light emission is extremely brief.When using the device, glide it over the area from which you want to remove hair, ensuring that you expose all the hair follicles in that particular region. Immediate results will not be noticeable. The light emitted by the device sends signals to your hair follicles, prompting them to cease growth. However, it will require multiple treatments spread over several weeks before noticeable results can be expected. Over time, you should observe a significant reduction in hair growth in the treated areas.In the box, you get the tool, a power supply, a protective bag, a pair of eye protection glasses, a cheap disposable razor, plus instructions. Everything fits in a custom "hat box" styled case. This case is too clumsy for travel (and doesn't have a clasp to keep it closed), so I consider it mostly for storage for home use.Ice functionality is another term for "Local epidermal cooling." This is local cooling of the epidermal region (surface skin) in the region where the IPL light pulse is being applied. The high-powered light can be irritating to some people, and cooling the skin in that region can reduce the immediate irritation. Epidermal cooling is not required for efficient use, but it may make it less unpleasant to use the device for some users.This IPL device is a bit on the high side of price, given the features. Those features include the ICE cooling, and that it is powered by a 48W power supply, which is better than the lower power usually associated with low end units.Note that the shape of this unit is a bit unusual--most of these are either gun shaped or more oblong. I didn't find it that comfortable to hold, although your mileage may vary.Summary:Pros:** Integrates epidermal cooling (ICE)** 48W power supply** LCD readoutCons:** Some may not find the shape as convenient to hold as others** Price is higher than other IPL devices with similar features
