Thunderboltex 4 Card

4th one I have bought and installed. Have 2 more to go.

4th Samsonite backpack we have purchased.

4 x 6 print pak is convenient and B & H is a reliable vendor.

4GHz ~ 4.7GHz self overclocking when power on and keep above 4GHz most time.

4 years I did not use new MacBooks. It is great progress. So many new technical characteristics.

4 memory cards fit safely and securely with ESD protection as well.

Great little handy portable item. It surprisingly solidly supports a Canon Mark III full frame camera with a 16-35mm III USM zoom. Strong and simple to use. Have also used this with the correct brackets to hold strobes (flashes). Rubber feet help with slipping on non level surface. One of my most used items. On another note, here is a gentle warning concerning purchasing this item or any others. At the time I placed some of my purchases, there were 4% rewards offered. This is 1 of the reasons Ive made some purchases. Upon waiting the allocated amount of time without receiving the 4% rewards, I reach out them via chat and phone only to be told these purchases do not qualify. Im very disheartened that this was not resolved in an honest mater since I am certain it was listed on the website during checkout. Ive done a price comparison at 3 different stores comparing the items Ive purchased since the beginning of the year and all are about the same price. I will unfortunately start looking elsewhere for my purchasing needs due to this dishonest practice. So this may be one of my last few reviews of some products Ive purchased here. Take care and keep shooting!

4 stop ND but as advertised. Know exactly how many stops used rather than VND with imprecise wheel.

Only by about 3%-4%, but still 6 cores are doing better than 8. Runs reasonably cool and no problems with games or professional apps like Photoshop or Lightroom. For most people wanting a fast enough computer without a big investment this is the sweet spot.

Bought this for use with the 70-200mm f.4 L lens. No degradation of image quality.
