I have a Spot-Hogg Sure Thing site and here is my assessment of it. Durability-Bulletproof. You could run this sight over with your car and still use it.

Ease of adjustment-Very good. The Sure Thing has threaded drives for gang adjustment and the individual pin micro adjustment takes some getting used to, but is very precise.

Visibility-Very good. It offers an excellent sight picture and the painted pin guard is very easy to center in the peep. The pins are as bright as any non-wrapped fiber optic on the market.

Value-Fair. They are an expensive sight, but I feel they are well worth it because they are made with quality components and well put together.

Hope this helps.
