IMO, Everlast has an inferior chassis design for shipping (vs Longevity)
The plastic front/rear panels, while attractive, provide no additional support when severe loads are applied (ie-shipping containers, UPS, FedEx, etc..). When the front/rear plastic panels crack/break, the 'box' itself will 'flex' causing the internals to respond unkindly (bend).
That said, so far my experience with Everlast tech support has been excellent (detached wire problem cured), & issues I have had to date (cracked front bezel-PP256) have been resolved.
