Pros: Inexpensive and reading speed is about 60 mbs by HD2 benchmark (using usb 3 port for testing, usb 2 will be about 25mbs)
Cons: Writing speed is about 18mbs in usb3 and 17mbs in usb2 with writing 3.7g large single file. I would expect the writing speed in 30mbs something because my Adata usb3 flash drive is doing 65 mbs in reading and 35 mbs in writing with usb3 port. The manufacturer is pumping up the reading speed by 25 mbs to 85 mbs by using the word "up to".
Other Thoughts: Just think about the price which is under 20 dollars. If I want to spend 80 dollars I could get one with 90 mbs reading speed and 60 mbs writing speed. Again 80 dollars vs 14 dollars for my 160 dollars smart phone is a quite heavy investment. It is almost 50% of the base value of my phone. So far I did not see any hesitation in my phone with this sd card. I guess it is ok for my phone with that kind of writing speed. Maybe my phone is not capable to write more than 20mbs to sd card.READ FULL REVIEW
Pros: It is not too expensive
Cons: During real life copying of large files, 4,5 g bytes, I only got 80 mb something in reading and 20mb something in writing. I never got the 100mb in reading and 50 mb in writing as the advertisement stated. I guess someone to jack up the specification to lure more customer.READ FULL REVIEW
This review is from: AGPtek iT4-2 Stainless Steel 150 mm LCD Digital Vernier Caliper Micrometer Gauge
Pros: Price is extremely cheap with comparing other caliper, nothing else.
Cons: After I used it for several days, one day I had a reading of 1.572 inches and the mechanical part of the ruler pointing at approximately 1.1 inch area. I hit the reset zero button, no effect and it still gave me the wrong reading. I have to took out the battery and reset it then fine. The voltage of the battery was OK within the operation range 2.9 volt.
This has been happened 3, 4 times and reading randomly switched from inch to mm by itself without my input. If I moved the slide rapidly from forward to backward then forward again, the caliper will gives me a wrong reading for sure. I did not mean a couple of thousandth, .3 inch more wrong reading.. I understand this is $12 caliper not 145 dollars caliper but some type reasoning reading should be there If the object is 1.500", I do not mind get a 1.502 reading but not 1.865. I am not going to send it back for exchange because it is only 12 dollars. Return postage and time are not worth the effort.
