Have used mine several times and am impressed with the quality, as always.
I do have the cheaper Russian Apex tool lab tool as well, which is OK for the price and occasional use, but feel much more confident with the hdd surgery tool which feels like it is generally better engineered and fits the head assembly more securely IMHO.
Sure, for “one off” DIY attempts or small DR companies then go for the Russian tool which is plenty good enough for that and has its place in the market, but for serious professionals and regular use then the hddsurgery tool is a “no brainer”!!!
I have no affiliation or axe to grind with either company
