Well, this is my second Pelican case. I've owned the small (carry-on compliant) 1510 for over a year now and absolutely love it!Besides this 1650 being HUGE (I can fit my 1510 case inside with room left over), it still complies with all U.S. airlines check baggage size limits (by 2-inches!). However, I must say that this case is also pretty darn heavy just by itself at around 30 pounds (13.5 Kilos). So, keep this in mind because, even though physical size of the 1650 is fine for checked luggage, the WEIGHT requirements are around 50 pounds (22.5 Kilos). So, you only got less than 20 pounds (9 Kilos) before going over limit and getting charged extra!I personally have loaded my 1650 with over 40 pounds (18 Kilos) of camera and lighting gear. All I can say is that I'm soooo glad for all the heavy duty handles in order to move this amount of weight around. And yet, once on its wheels, it's stupid easy to roll around fully loaded! The scary thing is, I have no doubt this 1650 can hold even more weight. Which would simply make it a two-person job lifting something that heavy.So, with that said, how about I just copy/paste my review of the 1510 from last year?I am completely blown away with the quality and features. This world would be a much better place if everything was made to this standard.Although it's a little expensive (especially for the 1650 model), I feel I got well over 127.38% return from my investment and have ZERO regrets from finally being able to afford this size of Pelican case. I plan on this case being with me for the rest of my life.Pros:- Outstandingly durable; I would trust my life with this product (literally)!- Large amount of space, and I mean a lot!- Heavy duty handles and latches- Lockable with metal-reinforced padlock holes- EVERYTHING proof (wind, water, sand, dirt, snow, elephants, airport baggage handlers etc...)- Quad roller wheels are easy, durable, stable, and low profile- Collapsible handle for wheeling around- Lifetime warranty- Able to carry heavy loadsCons:- Wish logos (branding) were a little smaller and less noticeable. I ended up using some photography gaffers tape to cover them
