### ⭐⭐⭐⭐⭐ Top quality beats a cheaper price
*by S***N on April 4, 2026*

Have used these for years and they are wonderful. Tried one of the generic products and was disappointed in the quality ( returned for a refund) so I went back to these. Will not be tempted to sacrifice quality for the price again!

### ⭐⭐⭐⭐⭐ Great value
*by B***N on April 3, 2026*

Perfect, great value and quick delivery. Being Simpson brand you rest assured it’s not a inferior knock off for structural ties

### ⭐⭐⭐⭐⭐ Looks like what you get at the home center and works just the same.
*by G***G on January 7, 2026*

I noticed these are slightly different in appearance (stamp on end looks a bit more washed out and harder to read on the batch I received) than what home depot carries, but that doesn't really matter since it's the exact same. A lot of workers make fun of these for their cost over nails, but boy these are great later when you make a mistake and need to take some straps/hangers down.
