My original write up was for 5 stars for the price and it read:

Glad we bought this set, and we plan to buy another.  For the money, we're ecstatic.  Have used them on four one week trips, and they've held up just fine.  This is my first time using the 4 wheelers vs. two.  I like the 4 wheels because they don't tip over when left alone and are great for moving along in lines.  They stick out a little more than the two wheelers, but I prefer this style.  I've had expensive Samsonite luggage, but the zippers kept wearing out.  This set was 1/5 of the price and seems nearly as well.  Was also pleasantly surprised at the compartment ergonomics - numerous well placed pouches.  Great set.

I'm writing an updated review now that the suitcases are about 4 1/2 years old.  I'm giving them 3 stars due to their useless warranty, poor quality wheels (see photo how one wore down to the level of the wheel housing/encasement), separating stitching, and especially for them shipping a defective item (see attached photo of poor quality wheel hole not centered causing the wheel to wear in just two uses) and expecting me to send it back with $40 for S&H.

The rear wheels on the two biggest suitcases have worn and need to be replaced, plus the stitching on one suitcase is separating.  The company has a 5 year warranty, but it requires that we pay for shipping plus $40 per suitcase for their shipping and handling (S&H), which is ridiculous considering you can buy the entire set for $160 = $40 per suitcase.  I even offered to hand deliver the suitcases to the address is California to avoid S&H, and they said, "We are not open to the public, this item will not be repaired it will be replaced."  It really isn't a warranty at all, but rather just paying for a replacement.  Also,they really need to use better wheels - especially on the biggest suitcases.

In the end, I decided not to utilize their worthless 5 year warranty.  I cut the wheels off with a hacksaw, and bought for $9.00 each two pairs of 45 mm X 18 mm wide Luggage / Inline Outdoor Skate Replacement Wheels with a 30mm axle to replace them.  I used the plastic that covers the wheel axle and melted it onto the improperly drilled hole with a soldering iron, and then drilled new holes.  So, I fixed them both for $18 with better skateboard wheels vs. paying $80 for them to replace the suitcases under "warranty",

They would be better off NOT advertising a 5 year warranty and saying we make an inexpensive, average product that is sold as is.
