I bought this with the intention of installing a lot of horse fences myself. It exceeded my expectations. It is not fussy, works well and can quickly insert and not pull out the brace. 3hp electric air compressor works well as does the 9hp gas compressor. If you fencing yourself and fencing a lot, this is a good idea. May not be cost effective if fencing less than 100 acres apart from age and physical ability. If the last 2 are an issue I would definitely consider getting one.
