I have the Sealey over priced equivalent back in mid 98 £33 after bargaining then, lasted two years before guides went. This has same head as the third one down not as piccied in 2nd down with camlock.
Now looking for a suitable donor or new guides, its just been sitting there for 10 1/2 years gathering swarf.
Mixed feelings on the camlock, thought at time push up to job and clamp which works well.
However theres a massive gap at end of vice area to the blade.
Use the Bimetal blades they last 4 to 5 times longer than the cheapies.
Mine will flip 90 degrees vertical and came with a flimsy bolt on plate (2 M5 countersunk screws what you cannot tighten up enough.) Emergency use only.
Of the three the 3rd down is the more robust due to the head.
