I purchased this lift along with the sling in Dec. 2009. It is in good condition and I also have an extra battery which is brand new. If you go to the following site it will give you all the specs. Although we had it since 2009 the only time it was used was to help him out of bed or into the shower chair. This is a product of Drive Medical, (Model No. 13240). The lift has an emergency manual lowering feature, a battery charge indicator and a pretty wide base. The base fit easily under the bed in order to position the body into the sling. I am a petite person and I had no problem maneuvering the lift around with my husband in the sling. The sling we bought for this lift was the Hoyer-4-Pt Padded U-Sling with head Support I paid $148 for it back in 2009. I won't be selling the sling with the Lift as it is used.
