I bought these hoping that since theyre bigger theyll be more durable. The compartments and size is great as carry onThings I dont love:It needs a handle on one end so you can easily pull it out of the overhead binI wish I could have it stand upright when Im wheeling it and need to stop to show my passport, etc. I mainly use this pad for hip hinging exercises and its great! li ho testati fino a due ore e più di corsa e la ricarica è durata perfettamente! It seems to work OK, so I decided to keep it, but be cautious of this vendor, as this was clearly a deceptively advertised product! And finally, I couldnt get this mike to work on my laptop. Meaning that even though these are an old model you can show bose the date you purchased them from amazon and that should reset your warranty. After hours of trying to fix it with Mint Mobiles technical support, I figured out that both Mint Mobile and T-Mobile consider the phone (identified by its IMEI number) to be incompatible with their VolTE service. I?m sure I would get use to the feel and it would be fine after awhile, but I?m picky. Third, the mount itself is close to 100mm without the end caps.
