I finally got Roomba running again,I love it!

Was quite impressed with the quality of battery and charger. I finally got Roomba running again. Low charging time and long running time: I love it! But shipping sucked! Please! Please! Please add a RED WARNING for U.P.S. Canada! Worst possible shipping choice: they wanted $44 extra on top of the $20 already paid and held my package for ransom. I escalated and paid only duty & tax but the driver refused to hand me the package and was rude. There's no communication between UPS departments! Spent hours on phone, 8 calls!
everything worked smooth

My experience has been fantastic, very fast response and adaptation to my personal needs. The item was sent at a lighting speed. As a critic instructions for the battery charger are not clear but everything worked smooth.

I was very pleased with the order process (web page organization, etc.), and quite surprised at how quickly the battery showed up. Appreciate your good service.
Easy as Pie

I like the Roomba but having to replace battery packs on an annual basis made it a little more investment than what I wanted. It was really easy to swap out the packs. Just follow the instructions. Now I need to order the trickle charger and another set of cells to replace another dead cell set.
highly recommend

I ordered the week prior to Christmas and the batteries arrived on the 24th. I am very pleased with the product and the service. I would buy again from this vendor!

What I wanted at the best price I could find online. Finding the right product on the site was easy. The checkout process was straightforward. Shipping and delivery well within the expected time frame. BatterySpace emailed me all the info I needed to track the order.

Very pleased. I had trouble with the order I placed online (my fault) and a phone call corrected the problem. I received the corrected order quickly.
