I understand the feeling of being overwhelmed by the sea of products and which one to go with. I bought 3 different e-cigs. RN4081, DSE901, and DSE801 - and now I'm wishing I had a Joye 510 from all the reviews I've read. But don't be scared! LOL.
Here's my advice, then.
1st. See if you can find Joye510 (it's called Yeti, Titan, Janty Dura C - but it's original name is Joye510) - and if you can find a steady supplier you can trust with all the parts and pieces, this might be the best optioin. Performance, price (50 US dollars), and I personally like the look. Little larger than 100's, but it does seem like this might be the 901 killer.
2nd. If you can't find 510 vendors in Canada - then go with DSE 901. Probably the most popular mini e-cig. Little larger than super minis, but very reliable, decent performance and all - and best part is that it's quite common, your chance of getting spare parts are better than others.
L88 probably means it's 88mm unit. I haven't really heard much of good reviews on smaller units. If you can get a refund out of it, I'd say do it and go with above 2 models if possible.
