First up & definitely the favourite with claims that this can last around 5 hours(!!), 'Victoria's Secrets Beauty Rush Gloss' (Available at www2.victoriassecret.com). Secondly & my own personal favourite is 'Mac LipGlass' (£10), 
it was a pretty close call between the top two but this one's lastability is still very strong, some claiming a good 3-4 hours! Last but not least Estee Lauder's 'Pure Color Gloss' (£14) was a preferred product by many, plus all three products come in a range of many colours to choose from, even better...!!!
Regardless of what product you use there are a few tips in making your gloss last longer - Firstly make sure your lips are in good condition, apply lip balm beforehand & if needs be exfoliate your lips (use a soft bristle tooth brush for this & rub away excess dry skin). Apply a little foundation to the lips, very sparingly & then gently pat a little translucent powder over the top, this will provide a good base to hold the gloss in place,
also try a lip primer as these work a little longer at holding your lippy in place, I use Benefits Lip Plump (14.50) under lipstick & gloss which works a treat at keeping everything where it should be!
