As promised doesn't leak. Isn't hot to the touch but contents kept hot at least 2 hours. Locking button makes sure mechanism cannot be pressed accidentally. You can use it with only one hand. Only downside is it doesn't fit my car's cup holders (but as it doesn't leak I can just keep it anywhere, including in my bag). It is on the small side, but enough for my needs. If you need it to last you more than half a day or you drink a lot of fluid, go for the West Loop model
2 X MICRO SIM CARD ADAPTOR ADAPTER CONVERTER TO STANDARD SIM
12 May, 2016
Does the job for a great price
I purchased this item because I potentially need two adaptors and there was only one provided with the SIM card cutter I purchased separately from another eBay seller. I am glad I did, because the other adaptor just mentioned is too thick and won't fit in the slots. These do work very well in the spare phone I intend to use them. However, I would use them with great care in an old style iPhone (whence 4 stars)
