Parts for an old machine
My brush cutter is an old model long out of date. I was surprised they had the parts I needed to keep it in service. Easy to find, order, and fast delivery.

Long Wait Time
I ordered parts for my Husqvarna chain saws in November 2019. On the ereplacementparts.com website all item showed shipping with 5-8 business days. Parts arrived this week; 3rd week in January, almost 2 months out.
I called on order several times, because my parts were needed to finish a lot clearing job. ereplacementparts.com held up the whole order due to one back ordered rubber bumper. Like many of my other suppliers that take a pro-active approach to order shipping, ereplacementpart.com should have realized a separate order should have been created for the back ordered item.
They finally did that upon my request 6 weeks in. They were quick in one respect; charged my credit card the full amount upon order acknowledgement. Also charged me extra shipping costs for the one back ordered item. You asked for a review, here it is. I will need more parts in the future; let's see if ereplacementparts.com steps up with a modest credit.
