from 1121 reviewsIncredibly fast delivery. Packed to protect the product. Great service.
Ultrafit Series 5 Air Rower spiral spring set Is a direct fit using Part #719495 (1000362015) for a Matrix AR II 2015 rower. All that is needed is to put the labeled sides on the opposite sides for use on the Ulrafir rower.
Fast Shipping. Item was like new and all I had to do was remove the old console, replace and plug in the replacement and start pedaling! I love having my screen again!
The High Cable on my Weider Pro-9645 was becoming frayed; the vinyl cable protector was worn, exposing the steel cable. At first I considered dismantling the equipment for the recycle center and just buying a brand new Weider home gym set. My partner said he could easily replace the cable as he has done in the past for the other long cable that controlled other stations. I was amazed that Hydrafiness Parts had the exact cable for this model, ordered it and we did the cable replacement ourselves. The Pro-9645 has been part of my main work-out routine since 2000 and remains good as new. I can highly recommend Hydrafitness.
I believe it’s a good product to purchase for the cost in the event something were to happen to the item you purchased.
The board that I received for my treadmill was protected very well and the functionality was not affected at all.
The wheels I ordered looked like original. Shipping arrival good. Price was ok. Easy to replace. I am quite satisfied.
Fits and works perfectly. Treadmill back in operation.
Interested in purchasing and refurbishing the console that was replaced? It is in good condition but needs some electrical components replaced. Let me know.
Thanks. Great service !!!
Exactly as ordered. Arrived right on time. Will buy from again!!!
Used motor in great shape, works fine in my treadmill. Saved hundreds vs buying a new one.
The part was easy to install into my exercise bike.
Great service
Replacement past went in smoothly, re hot glued wiring to out belt cover to eliminate noise following install.
This item was received in the time promised and it was properly packaged. I can’t wait to use it.
Exactly what we needed for our customer
