Pros: I didn't test the speed, but it seems to go fast enough for me. I have it installed in my Samsung Galaxy Note 4. I have put a number of movies and TV shows on this card and I haven't even filled 25% of this huge card (starts at 120 GB). I have also taken a number of photos & video and it doesn't seem to slow it down (photos = 16MP, 5312x2988 pixels) (video = 2160p@30fps, 1080p@60fps).

Cons: Lasted a little over 2 years in my phone. Died on 12/9/2017 and I started using it in August 2015. It's hard to find SD card that will last very long.

Overall Review: I just hope it lasts. I have had problems with other microSD cards (different brands) failing in the past. I have only had it just over a month.

Pros: Seemed to work fine for 5 minutes.

Cons: I plugged this converter into the DisplayPort of my laptop and used the DVI on my monitor. It worked for about 5 minutes then it stopped working and my monitor screen went black. I made sure all the connections were tight, checked settings, etc. It even started flickering on and off after I left it plugged for around 20 mins, but even that stopped and now nothing happens.

Overall Review: I have not tried the HDMI portion.

Pros: If there was a station 10-15 miles away maybe it would pick it up just fine.

Cons: It does not pick up many channels. The channels that it does pick up, don't come in very well. The description says that in picks up channels up to 50 miles away, so I figured the stations that are no more than 35 miles away would come in just fine, but they don't. A local station (WTNH channel 8), which is no more than 20 miles away comes in a little, but it’s unwatchable unless you hold your hands on the antenna.

Overall Review: I have an apartment in Guilford, CT where there are only tiny hills and most of the stations are 35 miles away in Hartford, CT and less than 20 miles away in New Haven/Hamden, CT area.
