Review: Great product and delivery - These batteries were delivered on time. They work perfectly. I don’t know why this order still reflects a delayed delivery. My husband is using them in his Ryobi tools. I think the UPS tracking numbers got mixed up; the original tracking number was not the one on the package when delivered.
Review: Great customer service! - I had ordered the 40V 4.0Ah battery, and it worked out of the package. Because it was February, I didn't need to use it right away. Unfortunately, it wouldn't charge, and I wasn't aware of the problem until after the 30 day return policy. I wrote the vendor, and explained what happened, and they replaced it at no charge to me. I've been using the blower and trimmer with this battery since then, and it works perfectly. Things go wrong at times with everyone, but what a vendor does to fix it is what makes a company good or not. I would not hesitate to buy from this company again!
