TECSEE Blue Sky Cloud switches housing feature a full HPE housing. The material offers smoothness from that of UHMWPE, with an appearance close to Tecsee's other switches made from PME. Sound wise, these are rather similar to that of milky housings from Gateron but with an added crispness, as opposed to the more muted and subtle milky housings. Many UHMWPE Switch users reported the stem because it is too soft, with time it can get smaller and loose. The new HPE material features a soft, smooth feeling and comfort without deforming as easily as the old version. Very smooth linear switches with 63.5g two stage, 22mm long springs. The switches also utilize a long pole stem for a solid bottom out sound with very lightly lubed and while they are ready to go on any mechanical keyboard, those inclined to tune their switches will find an excellent starting point.
