"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Excellent work. We purchased natural cherry cabinets in shaker style, with the panels made of solid wood rather than veneer. That is more difficult work, as each panel has to be constructed from several planks. Moreover, the clear finish would leave any flaws more visible. Simply put, the doors are beautiful--flawless in both construction and finish. They are similar in quality to custom cherry furniture we own."
