David CordovaHigh quality excavator boom with good price! I like it very much, so I brought 2 units of demolition arm again. The whole process went smoothly. Next time I need to buy excavator arms, I will buy them from here.
Vaina ConroyVery happy with the service provided. All questions were answered promptly. The product was as described and arrived on time. Great packaging. The biggest surprise was that the welding quality of the product exceeded my expectations.
William HollisterVery helpful. The excavator long reach arm I purchased are solidly built, well made and I have no doubt they will last for many years.
