Can’t Fault Best Fitness

I normally don’t review products but have to give credit where it’s due.
1. Excellent customer service - Best Fitness emailed me after ordering (10pm) pointing out I ordered 1x weight stack upgrade for functional trainer but would need two. They asked if I meant to order two, which of course I did, can’t upgrade one side only. They adjusted my order so everything would arrive together.
2. Quick shipping - Order delivered in ~36 hours!
3. Good value - For equipment that’s towards the lower price range it’s good quality and solid. In my opinion suit all but the heaviest domestic use.
4. Easy to assemble - No problems for us, the bench was the best just popped out the box ready to go pretty much.
I ordered from Best Fitness based one the price and good reviews.
I highly recommend Best Fitness.

Always happy.

Quality is outstanding, price is always so good and get my stuff the very next day. Amazing
