We present the state of current research of Very Short Gamma Ray Bursts(VSGRBs) from seven GRB detectors. We found that VSGRBs form distinct class ofGRBs, which in our opinion, in most cases can originate from the evaporatingPrimordial Black Holes (PBHs). Arguments supporting our opinion: 1. GRBs withtime duration (T90) < 100 ms form distinct class: VSGRBs. 2. We observesignificant anisotropy in the galactic angular distribution of BATSE VSGRBevents. 3. V/Vmax distribution for BATSE VSGRB events indicates the localdistance production. 4. VSGBBs have more energetic {\gamma}-ray burst thanother GRBs with longer duration (KONUS). 5. We observe small number ofafterglows in SWIFT VSGRB sample (25%), in contrast with the noticeableafterglow frequency in SGRB sample (78%). 6. Time profile of rising part BATSEVSGRBs is in agreement with the evaporation PBH model.
