This is Remington's top tier home IPL system: their "most effective and most powerful," as the ad copy says. Low usage--around 15,000 to 20,000 pulses--it is rated for 300, 000 pulses, so it has plenty of use left for effective treatments and it does prevent hair growth really well (please be mindful of the ideal skin tones and hair type/colour for effective treatments: it works best on light skin tones with dark hair). In perfect condition cosmetically and functionally. Cost me close to $1000 new. Comes with box and alternate treatment cap. I currently cannot locate the instructions (still looking for them), but the user manual is available from multiple sites online.
