Review on Mifold Grab-And-Go Car Booster Seat, Denim Blue - Compact & Portable For Travel, Carpooling And More - Foldable Child Booster Fits Into Glove Box & Backpack by Antonio Moore

We ordered 2 of the same color at the same time. Date of manufacture is one month apart.HOWEVER.the 2 units are NOT the same.- One unit has the adjustable sides that only lock outward, but not inward and will easily slide back in. I think this was the initial design based on all the reviews I have seen.- The other unit does not have that same design so the sides do solidly lock in the position they are set at. It appears they have been updated to keep them from sliding inward as well. I am guessing this is when the design may have been updated.This is kind of annoying because I really like how the second unit operates. I am honestly considering purchasing another locally instead of on Ebay to insure I get a newer unit with the updated design. The change makes a big enough difference to consider it.2 other issues that can be a problem.- In certain contoured seats like the Audi we had, the rear portion of the MiFold does want to fold upward which changes the fit for the child and can be uncomfortable. There are videos on how the MiFold should be placed in contoured seats versus flat seats. WATCH THEM. Be sure to explain that to your child when getting in so they have the right fit every time. You may have to assist them.- Your child may complain that they are uncomfortable. I think a lot of this has to do with initial placement int the seat.My children didn't like them at first, but once they were well versed on how to use them, they didn't seem to complain anymore.We just went on out first trip with these and used them for about a week daily. My kids are 4 1/2 and 7 1/2. There was a learning curve on getting the kids set up with these. After a quick YouTube visit and showing the kids what to do, we were good. By the end of the week they were able to get themselves in an out of the car on their own. That's a win. ***Be prepared to explain and/or show to Rideshare drivers or others that these are safety/booster seats, but rather than bringing them up to seat belt height, it brings the belt down to them. Also make sure these do follow your local child safety laws.***In the end we though these were great for travelling. We liked the size and ease of use. The kids seemed to like them too. Would I buy them again.YES. Would I buy them from Ebay without knowing which version I would get.NO. BuyBuyBaby and others carry these for not much more and I would do whatever you could to get the new version. I will try to upload photos later of the difference between our 2 units.
