ECHO Echo 99944200907b New Genuine Speed Feed 400 Head fits All SRM Trimmers!!

I bought this as the product was said to fit all SRM models. However the screw thread is much bigger than the thread on my Echo SRM 345SL so it is completely useless to me.

This genuine Speed Feed 400 head is a perfect fit for my SRM trimmer and works exactly as advertised. Installation was quick and easy, and it was ready to use in just a few minutes. The best feature is how fast and simple it is to load new trimmer line. I can reload in under a minute without having to take the head apart, which saves a lot of time during yard work. Once loaded, the line feeds smoothly and evenly with no jams or tangles. The build quality feels solid, and after multiple uses it still operates like new. It handles heavy grass and weeds with no problem and keeps the trimmer running efficiently. One thing to note is that it did not come with the adapter parts needed to fit other brands, so if you plan to use it with a non-SRM trimmer, you may need to buy additional hardware. For SRM trimmer owners, it is a great upgrade, but anyone using a different brand should check compatibility before purchasing.

So quick and easy to load cord. Awsome whipper snipper head!!

OEM. Works as it should. . Installs easily.

Excelente calidad del material y la facilidad para cambiar el hilo

It does the job that it is supposed to do. But only for an Echo weed trimmer. The equivalent store bought unit is identical to this unit, and it includes adapters for other trimmer manufacturers at a higher price. Since I only needed it for my Echo trimmer, I purchased it at a discount price compared to the packaged store version with adapters. Do your homework before buying such a unit and make sure you know if you need adapters before you purchase any like item, sight unseen. I would buy from this seller again. Thanks.
