I received my Leg Extension Leg Curl a while ago but have not been writing a review because I was having issues. One of my front legs was lifting up during use. I contacted KINGSMITH directly and they quickly emailed me back offering to fix the issue. They ended up asking for a few photos and sending me a replacement unit that they thought would fix the problem. The replacement unit they sent did not fix the problem and after letting me know, they were willing to send me a brand new unit to replace my current unit. I can't express how helpful the customer service was throughout the entire process.

I wanna make it clear right from the get go. I purchased this item a 25% discount, so keep that in mind. The pully lever system on this thing is the selling point and that delivered. The cam, pully, and bearings are that of a much more expensive machine and are worth the money. Its real smooth and the load is contant throughout the motions. I'm 5'7" and it can stretch my quad and hamstring very effectively.

KINGSMITH kills it yet again with another quality product! Everything came, no missing parts and was delivered before expected delivery. This will be my 3rd KINGSMITH product and I must say, they are great to deal with! Will always buy from them!

I placed my order on May 12th and it still hasn't arrived.
Dear Jorge,
Good afternoon, and thank you for reaching out.
Please rest assured — we understand your concern and would like to clarify the situation.
This is actually the issue we proactively informed you about earlier. The first shipment, originally sent on Monday, May 12th, 2025, did not show any logistics updates for over 10 days. Believing it may have been lost, we decided to cancel and recall the shipment to avoid further delay, and re-sent a new package to you on May 21st. We also sent an email on May 21st to notify you of this replacement.
However, unexpectedly, the tracking on the original shipment updated on May 22nd, after the cancellation was already in progress — and unfortunately, FedEx cannot reverse the recall once initiated. That is why you're seeing a message now indicating the first package is being returned.
But no worries — your new shipment is on its way, and estimated delivery date: between May 28–30
Canceling and reshipping was a precaution we took to make sure your order reached you as soon as possible. We sincerely apologize for any confusion or inconvenience this has caused and appreciate your understanding and patience.
If you have any further questions, feel free to reply at any time.
Warm regards,
Kingsmith Strength Team
