Unlike Aimpoint, which came with a rubbber protective cover and flip-up lens covers for the same price as Eotech, one has to buy lens covers for Eotech after market. GG&G sells them, but after buyng 1 on E-Bay that did not fit the XPS3 (although advertised as an XPS-series cover) and buying a 2nd one directly from GG&G, I am left disapointed. The cover was designed to fit XPS2 and is short for fitting under the XPS3 hood. Even after some "modifications" (like making a razor blade cut in the cover side pannels to allow for stretching in order to mount), the GG&G cover just won't stay shut. Wrote GG&G an e-mail to ask why are they selling a miss-fitted product, but got no reply... Anyway, for the price, Eotech should include it's own lens covers.
In summary, I'll probably end up selling the Eotech and buyng Aimpoint again
